However, I actually don't mind and quite enjoy the music change in the end celebration scene...actually felt it fit better with that scene and sounded more meaningful and fitting as the end to a whole epic saga/journey.
Anyone else agree?

I agree that it's a nice piece of music, but I disagree that it fits well in ROTJ. All of the films score have been "orchestral" until that point (except for when there is a band playing within the films... Jabba's Palace for example) and then BAM there's this unprecedented "new age" music complete with a loud bass guitar. Completely flies in the face of, and doesn't jibe with the scores of the rest of the films. Again, except for "Jedi Rocks" (which, while awful, takes place within the film, rather than being part of it's score) I can't think of any other "new age" music or bass guitar in the other films. To me, it just doesn't work as SW music. YMMV.
