Being John Malkovich. Trust me.
Music: The Best of Al Jolson
Movie: Suspiria
I seem to remember Yes’ “Close To The Edge” (music) and “Quest For Fire” (movie) being an interesting combination. Also, almost any Pink Panther movie, especially at a drive-in.
Allman Brothers (if you get the DVD “Live at the Beacon Theater” you get music and a movie)
Nektar - Remember The Future
Quadrophenia
Blind Faith
Golden Earring - Moontan (esp. side 2)
Santana - Caravanserai
Traffic - Low Spark or John Barleycorn
Robin Trower - Bridge Of Sighs
I think some Grateful Dead (Wake of the Flood, maybe) and some Doobie Brothers (try The Captain And Me) are pretty much mandatory.
I don’t remember cartoons so much, but Monty Python works Really Well. “Harvey Birdman, Attorney At Law” might be pretty funny stoned. Or “The Tick”.
Any music that I enjoy is improved with pot. But I’ll give some examples of stuff that is particularly intensified by it, stuff that would blow your mind sober, and straight-up takes you to another dimension when you’re high.
Oh yeah, and if anyone here has heard of any of these bands, say so, so I don’t feel so lonely here.
Tortoise
Pele
Amon Tobin
Booka Shade
Shpongle
Sound Tribe Sector 9
Air (specifically Moon Safari)
Squarepusher
Deep Forest
There are some classics too:
Getting high and then listening to the album Can’t Buy A Thrill by Steely Dan for the first time gave me a feeling not unlike how I imagine the first man to walk on Mars will feel.
It wasn’t until I smoked and listened to Abbey Road that I discovered that the the transition between You Never Give Me Your Money and Sun King is supposed to sound like being in a crowded, noisy party (the fade out of YNGMYM), then stepping out onto the porch, and being in the backyard with the crickets chirping (the fade-in of Sun King) - and when the opening line of Sun King began, it was like floating on a fucking cloud.
Oh man…
Wow, were you smoking as you wrote this? Pretty intense words.
Nope, I wasn’t smoking as I wrote it. And I wasn’t high while I wrote it either. 
I never forget memories from drug experiences, though.
John Coltrane, especially the later stuff with the quartet. Meditations is mind-blowing. Listening to it baked is one of the few things I’d consider a spiritual experience. (Not that I do that kind of thing any more.)
In the album “A Child’s Garden of Grass”, they recommend Myron Florin music and Dick Contino music, but never [Unintelligible name] music,which is a weird combination of Florin and Contino, one version in each ear.
To listen to: Flaming Lips, Super Furry Animals, Jefferson Airplane
To Watch: The Big Lebowski, Lost (yes, the TV show), Any cartoons (South Park, Family Guy, Robot Chicken), That 70s Show.
I miss being a student.
Well, since you asked… I’ve heard of (but not heard much of) STS9 and I enjoy Air greatly! My favorite is the Virgin Suicides soundtrack, though… although it’s much darker, it’s just that much more intense. From your Abbey Road description, it sounds like it might be right up your alley ;).
And seriously… ONE person likes to put on the Dead? Geez…
Movies: Edward Scissorhands, Beetlejuice (I guess I’m showing my (young) age…)
This just reminded me of how one of my friends made the mistake of watching Requiem for a Dream while stoned.
He didn’t smoke pot again for awhile.
From ages 17 or 18 through about 22, I saw Cheech and Chong’s Up in Smoke probably 150 times, always while high. For music, I LOVED listening to Zappa, particularly his funny stuff, specifically Baby Snakes.

However, like the OP, I think that Bob Marley is PERFECT. Better than any other Reggae I’ve ever heard, stoned or not, but true perfection stoned.

If you’re looking for some music to smoke out to that wasn’t recorded between 1967 and 1977 snerk, there’s some nice minimalist/ambient stuff out there today that’s great, e.g. Sigur Ros, Frou Frou or Postal Service (surprisingly good considering I don’t really like Death Cab For Cutie).
There’s just a generation gap really. Older folks connect marijuana with the scene and culture surrounding it in the 60s and 70s. We, on the other hand, have no strong cultural or social associations with marijuana - it’s easily available and widely used among all young people and all music scenes. There’s no “typical” music for pot smokers anymore - you listen to whatever you listen to, and if you happen to smoke, then the music is enhanced for you.
Pretty much any good music is improved with pot. But some people like to have relaxing, chilled out music when they’re high, and others (like me) prefer highly complex and layered music because the weed helps them sort out all the individual layers and appreciate them more clearly.
This is a great observation. In my case, though, I had to change music once I got into marijuana and other substances. My preferred forms of music (at the time, mostly old school punk rock and thrash and a little bit of death metal) all sounded like jackhammers and Skil saws when I was high. I needed to get some gentler, more atmospheric music. “Music with no sharp corners,” I believe I called it in a moment of clarity to no one but myself. 
While I don’t think you’re wrong about the “generation gap” thing, I don’t think it’s entirely accurate, either. The examples I gave were all music from the past because my smoking was all (mostly) from the past. While I listen to some music from the current era, I can’t say with any personal experience whether or not it applies to the question at hand. So I kept my guesses to myself.
But, after reading you’re list and the second paragraph of what I quoted, I’d be curious to know what you think about the following music. (It’s the “highly complex and layered” part that makes me think you might like some or all of them):
Zilla
IQ
The Flower Kings
Transatlantic
Spock’s Beard
Gordian Knot
Riverside
The Tangent
moe.
String Cheese Incident
The Derek Trucks Band
just to name a few
Yes, and no.
One of my worst weed experiences ever was after smoking a little too much, listening to my own band over a really nice system (not an ego thing; I was with a group of friends and it was in their iTunes). The thing is, the song had two or three layers of me singing, and three or four of me playing guitar. Everything was crystal clear because of the speakers, and of course thrown into hyper-sharp focus because of the weed. I freaked out. It was something about hearing two of me singing at once, and three of me playing the guitar at once, that just melted my sanity. It was a mushroom-like experience without the mushrooms. :eek:
Probably why I now prefer very minimal music. 
As my username may suggest, I’m a Pink Floyd fan. Back in the seventies, I used to get out my LP of Dark Side of the Moon, set the turntable for endless replays, light a few candles and maybe a stick of incense, and feed my head.
I can dig prog rock but I’m not a fan of traditional “jam bands.” Maybe I haven’t heard enough of it, but I don’t really find it to be interesting. I like the bass playing of Mike Gordon of Phish but I can’t take their silly lyrics.
I have formal music education and so I personally approach music in a much more hardcore and analytical way than most people. The first time I listened to Abbey Road high, I realized it was basically classical music. The structures and motifs are all lifted from classical, and traditional English band music. I wouldn’t have come to this realization like that if I hadn’t spent 6 years in my youth playing in both band and orchestra, and had been given private music theory lessons.
I don’t need to have complex chord changes or rhythmic sorcery. I just need to have a good, powerful groove, and interweaving lines of melody. The bass lines have got to be creative. I’m a bassist so I focus more on the bass line than most people do. I definitely prefer melodic bassists as opposed to strictly rhythmic bassists (this among other things is why I can hardly listen to any popular indie rock. Most of it seems to have the bass just playing the root note.)
Instead, I’m gravitating much more towards modern prog and what is known as post-rock. I hate the term “post-rock” because I think it’s horribly pretentious, but I’ll use it anyway because hopefully you’ll click that link and be introduced to some amazing bands. Particularly, I’ve been listening to Pele (I heartily reccomend you use iTunes to buy the whole album The Nudes if you want to have your mind blown.) I’m also big on Tortoise and The Sea and Cake. I am in a band called Bridge which plays in this style of music (we’re going for a mix of Explosions in the Sky and Tortoise in our sound - delicate acoustic melodies of the former combined with driving, powerful bass grooves of the latter.)
However, this isn’t the only thing I’m into at the moment. Lately I’ve been listening to a lot of Silversun Pickups, a current band with a very mid-90s revival sound, lots of distortion and a lead singer who sounds like Billy Corgan’s brother. Their best song is Kissing Familes, which anyone who misses the Smashing Pumpkins of the Mellon Collie era should definitely listen to.
