FFXIV has great music, the OST is pretty good! There are almost 80 tracks or so...
(i did listen to all on youtube)
However... The best tracks you barely get to hear and some of those that you hear a lot i do not like much.
Market wards music for example is really not my cup of tea, it sounds a bit like some bossa nova demo sound that is included in keyboards... Also the battle music in the mines is rather weird...
