Just found this, and OMG, it's awesome.
Basically it's a countdown of Beatles songs. All 185 of them. O_o
http://magazine.jamsbio.com/2009/01/05/playing-the-beatles-backwards-the-ultimate-countdown/ Almost each song has a youtube vid attached to it so you can listen to them (and watch the hotness that was John, Paul, George and Ringo).
It's so amazing, even though I know all these songs by heart, of course, but sometimes it's so much fun to watch videos.
F*ck, I love them. ♥
