Along the lines of “Name That Tune” where you wager you can identify a song (or tune) in progressively fewer notes, what songs can you identify almost as soon as they start?
A few of mine:
Elvis’s “Teddy Bear”
Pink Floyd’s “Money”
Gregg Allman’s Laid Back version of “Midnight Rider”
Peter Gunn Theme
The Doors’ “Riders On The Storm”
Lynyrd Skynyrd’s “Sweet Home Alabama”
Elvis’s “Don’t Be Cruel”
and probably dozens more.
Yours?
“Rock Around the Clock” - Bill Haley and the Comets
Deep Purple “Smoke on the Water”
This isn’t really an intro, but I can identify that little ding noise at the beginning of Depeche Mode’s Personal Jesus.
Here are a few recent ones I can think of:
Peter Frampton’s “Do You Feel Like I Do”
Garth Brooks “Thunder Rolls”
Bruce Springsteen’s “Born in the USA”
Grateful Dead’s “Casey Jones”
Louis Armstrong “What a Wonderful World”
Layla
Yep, almost any Beatle song,
I remember one Name that Tune when I heard
[sup]Hey[/sup] [sub]Jude[/sub]
“(Don’t Fear) The Reaper” amongst hundreds of others.
Kinks – Lola (That first chord is immistakable), All Day and All of the Night
Springsteen – Rosalita (another distinctive chord)
Deep Purple – Smoke on the Water (three chords)
Stones – Sympathy for the Devil (drums)
Traffic – Paper Sun (drums), Glad (drums), Light Up or Leave me Alone, Low Spark of High Heeled Boys (once it fades in)
Pink Floyd – Money, Astronomy Domine
Allman Brothers – Statesboro Blues, Whipping Post (bass), Midnight Rider, Hoochie Coochie Man
The Who – Baba O’Reilly, Pinball Wizard, Sally Simpson
Led Zeppelin – Good Times Bad Times, Communications Breakdown, Stairway to Heaven, When the Levee Breaks
Jethro Tull – Aqualung, Bouree
Beethoven – second movement of his 9th symphony
King Crimson – 21st Century Schizoid Man (if you start with the actual music – there’s a weird intro that’s hard to hear)
That’s just scratching the surface. I’m usually pretty good on any song before 1975.
Sweet Leaf
Sweet Child of Mine.
I passed somebody at work who had that intro as the ring tone on his cell. It almost didn’t make me want to strangle him for not having it on silent…
Any Postal Service or Radiohead song (from OK Computer, Kid A, Amnesiac, or Hail to the Thief.
Rolling Stones – (I Can’t Get No) Satisfaction.
in one note.
If it’s been on classic rock radio, I could probably identify it pretty fast. Extend that to any Allman Brothers song or Radiohead song, too.
I’m guessing pretty much anyone could recognize “Paranoid” or “Iron Man”.
Europe- Final Countdown (which is playing in the background right now)
I remember a “Name That Tune” segment on an Opera radio show…
The host hinted that this was a famous aria, and then played a single long note on the piano - one of the contestants rang in immediately with the correct answer.
Hint:
The note was the Ab below middle C
Anybody care to try?
dances out with knife in teeth, fanning decks of cards and dropping scarves
For the OP: aside from what’s already been mentioned (although ditto especially “Sweet Home Alabama” and the Beatles), most of the Beach Boys’ middle stuff.
Me too. 
There are a lot of songs that I can id from the first 1-2 seconds but the Personal Jesus ding is a lot faster than that.
Other songs that are more or less hard wired into me so that I recognise them at the first sound are:
Nine Inch Nails - Closer (the beat at the beginning)
And One - Deutschmaschine
Invincible Spirit - Push
Yazoo - Don’t Go
One that is identifiable from the first note/chord: Bennie and the Jets
