Thats a point, do you think there gonna recycle the old stuff, or make new music? (Can't really remember if they made new music for prequels - think they did) New music would be cool.
And apologies for the stream of messages, it was pg 3 last time I checked.
They really should make new music. Maybe use a few of the older pieces. Pieces that are in pretty much every movie should continue to do so. John had to start from scratch for the Prequels, creating new music for the characters, plot points, and planets. So he shouldn't have too much trouble making new music for the new movies.
