I think 2.0's music in some places really is more fitting.
Yet some of the reused tracks from 1.0 are really really fitting in ARR, such as some boss music and the final job quest.

What I really want is; Dual Layered Music Tracks

[ Out of Combat Theme]
[ In Combat Theme]

In 1.0, dungeons for example did this where two tracks played in and or out of combat, which was nice for some areas. I dont believe in having it in every area though (dungeons/raids, yes).

For areas, some of the tracks are too short, some are 'just right' as SOKENs team agreed on not having a constantly repeating track. For the most part, i'd think having it limited to 30-40 second music clips is kinda crap, then running in silence for the next 5-10 minutes.
