It's a very tough choice.
For me, the tracks I like are more important to my liking of the soundtrack than the soundtrack itself. The whole soundtrack being terrific is an added bonus.
My favorite tracks, in no particular order, are:
-hedwig's theme
-the face of voldemort
-leaving hogwarts
-harry's wondrous world
-across the stars
-fawkes the phoenix
-buckbeak's flight
-aunt marge's waltz
-rey's theme
-kylo ren's motif (not really a full track)
-jedi steps & finale
Yes, I haven't listened to all of the soundtracks from the 2000s, so my choices are a little limited.
What soundtracks or tracks does anyone think I would like based on these tracks?
