In my sophomore year, I declared U2’s “Mysterious Ways” my theme song.
Imperial March.
The Talking Heads’ Crosseyed and Painless.
When I walk around campus, I tend to think of “Lightning Twice” by You Were Spiraling as my walking around theme.
Of course, my official theme music will always be “Flagpole Sitta” by Harvey Danger. Sing it with me now, Teeming Millions:
*
Been around the world and found that only stupid people* are breeding…*
*excluding, of course, any Dopers who wish to reproduce. It’s different somehow.
In general, it would be “Eleanor Rigby” by the Beatles. Or “Namistai” by BT. “Have you Ever” by The Offspring.
For an upset mode, it would be “Push It” by Static x. or “Just Got Wicked” by Cold
For a depressed mode, it would probably be “Fall Apart” by NIN, or “Teenage Suicide” by Unwritten Law, Or “Amazed” by Offspring. OR “Where the Birds Always Sing” by The Cure
Happy: “If You Want to Sing Out, Sing Out” by Cat Stevens. Or “Duck and Run” by 3 doors down
Depending on my mood…either
The Imperial March
The Raiders March
Superman’s Theme
Axel-F
Mirrorshades
or Linus and Lucy
I think Chef Troy has the right idea here, but others have suggested changing with their mood.
For those upbeat times, I’d go with old 1920s jazz. (Bix!)
For making an entrance, maybe Duke of Earl would be good.
For depression, I wouldn’t change a thing.
Whenever I’m running on the track, field, or roads, I’d have the Rocky theme music playing.
Standing in front of a mirror or painting my nails or shopping - I Enjoy Being a Girl
I like rjk’s idea of 1920’s jazz for upbeat days. That or Irish step dancing music.
For mellow days: In the Jungle complete with backup group.
“Am I the only one here who walks around imagining the Charlie Brown theme playing all the time?”
You were until I just read that, Thing 1. (And now I have the Thing 1 and Thing 2 song stuck in my head)
Actually Sakura, Thing1 wasn’t, especially since I have Linus and Lucy as part of my car’s CD standard set.
They’re the first famous band I met. Nice guys. Last time I saw them the bassist remembered me and signed my promo poster “These are not my pants. Aaron.” with an arrow pointing to his pants. Heh.
I’d have to go with the Theme from Rocky for my entrance music. When trying to psych myself up, I think of Paul Simon’s I Know What I Know, specifically the following line: “She moved so easily, all I could think of was sunlight,”
Hmm well for me it could be one of several…
Lightning Crashes by Live
Believe by Savatage
If I Go Away by Savatage
With Arms Wide Open by Creed
and if I’m kinda depressed… Lullaby for Cain by Sinead O’Conner
Actually all of those are slightly dark in their own way… maybe that reflects my feelings? shrugs
Good day:
Friends in Low Places (live version)–Garth Brooks
Bad Day:
Hell’s Bells or Dirty Deeds Done Dirt Cheap(live versions)–AC/DC
I think I know mine…
Welcome to the Jungle, Guns n Roses…
Riders on the Storm- Doors. Depending on the setting anyhow.
Ah, and Tubular Bells, Mike Oldfield.
“Bad Company” by Bad Company. The title alone says it all.
Tough one… my first thought was “The Joker” by Steve Miller, but now I’ve decided on “Get Ready” as performed by Rare Earth - five-minute drum solo included.
My work theme is “A Day in the Life”, by the Beatles, and “Loser”, by Beck.
My love themes are “Walking in the Sand”, “Time in a Bottle”.
My triumphant entrance songs are “Heroes” by David Bowie, and “Funeral March” by Chopin.
My bad mood themes are “Criminal”, by Eminem, “Live and Let Die”, by McCartney, and “Fight the Power”, by Public Enemy.
My travelling music are “Take the A Train”, by Stayhorn/Ellington, “MTA” by The Kingston Trio and many other songs with trains in them.
Now I will have theme music playing in my head as I read people’s posts…
When I don’t have Robert Johnson or Buddy Guy playing for me it is usually “Hair of the Dog” by Nazareth. It works well on good and bad days. (There’s no offense intended towards my mother of course).
Rick, you need to have that ego checked. 
Pink Elephants On Parade
Hippity-hoppity, hippity-hoppity!!!
Sex Machine by James Brown. Or a Mexica Mariachi(sp?) band singing over and over, “please have sex with this guy.”
JB
Ooooh, mine do change daily - but if pressed to choose one for, say, my fantasy talk-show appearance, I’d have to go with something by The Cramps. The Way I Walk comes to mind - but so do Rockin’ Bones, Can’t Find My Mind, and Jungle Hop.
(Ike, I’m guessing that’s not the “Icandigit shecandigit hecandigit canyoudigitbaby?” one.)
