So i work in sales, and every time my rep gets a deal in, 30 seconds of a song of my choice gets played through speakers throughout the entire office. At the moment it's This Charming Man by The Smiths which is a bit rubbish. I need a song that has:

a) "indie cred" (but not to obscure)
b) a sense of celebration
c) a good introduction (we only get the 1st 30 seconds)

cheers
