Wow - really surprised to see there wasn't a thread dedicated to recommending soundtracks so I'm stating one with a soundtrack from an old movie - I Am Sam (2001).
I've had the CD forever but recently pulled it out and have really been enjoying it. I forgot how much I liked it. This soundtrack is all Beattles covers and there are some great performances: Eddie Vedder, Sheryl Crow, Ben Folds, The Vines, all with interesting interpretations of the original Beattles song. Never saw the movie but love the music.
