There should be one where you enter the tune yourself, last night's dream involved me listening to a CD or the radio and I can still hear the chorus clearly in my mind but I've no idea if I've made it up or heard it elsewhere!

Just invent a cybernetic interface for http://www.shazam.com/ and you're sorted

if you can remember the chorus - google it!

Solder a usb port into your brain, done, copy it to your pc, then ask on here if we know it

Isn't there an iphone app that you can sing in to and it tells you what the song is?

{edit} Yes there is, already posted by RazMan

I've looked up what lyrics I can remember, nothing appears to match... If I can get the rest of it out of my brain I think I might have a great political hit about the state of the environment

I think you'll find Billy Bragg beat you to it
