Did you ever hear a song (or part of a song) in a movie, or a movie trailer, and think “Gotta remember that”?   Of course, easier thought than done sometimes.  Case in point:  lots of great songs in Hop, but not on the soundtrack!  So, a quick internet search and — wow — found a great site for getting the name of that song you just have to have for your collection (or to ease that nasty “I can’t remember” itch).   The site is http://blog.songdetective.com.   Try it — I did and it’s just great.
