The credits always get interesting music, sometimes great, other times, unremarkable, sometimes awful. I think the ones in the earlier sequels were so good. The music at the end of 5, and 4 and 3 would just melt my heart.
But which was the best?
Mine would be...the music from 5. Man, I want that music sooooo bad!!
But the music for 3 comes in second. I remember being really touched as a kid when it was played, like I was with 5. I also liked how both movies used a nice shot of the valley at first, rather then just having it play over black screen (well, 5 did eventually and 3 I can't remember), and I remember being very disapointed upon seeing 2 and the credits just being to the same song as at the beginning. But hey, this was just when the sequels were starting, so I can give the a break. It's the later ones that have songs I don't like. <_<
