Okay, let's start with this nicest mashup.. this is actually one of the best mashups I've heard.  Well, every mashups they created in this movie is perfect.. can you pitch something that is not?

I tried to arrange it according to their sequence in the movie, and yes, I watched it again to do that.. well, it's a pretty nice movie and I haven't seen this in months.. and I can't wait for its sequel to come out in May.

Oh, and uh, I even added some of the songs from the movie which aren't part of the soundtrack list.  I think they're too awesome not to be included.
