On Music: SongFacts.com
Wanted to turn you all on to a pretty cool site I discovered called SongFacts.com. Lots of in-depth trivia about your favorites, including this 10,000-word tome on The Who's "Baba O'Riley" (That's "Teenage Wasteland" to you and me.)
I especially like the extensive, interactive element of the site, where users get to add their own two cents. Check it out now (the funk soul brother).
