FFXIV's music is amazing. Some music I don't really like (ex: Gold Saucer theme or the cathedral music in played in Saint Reymanaud's Cathedral), but that's a matter of personal taste. The primal themes are all top notch, and I even like most of FFXIV's themes and background music. In most MMO's I've played the music is "meh" at best, so I make it a habit to mute all sounds and music and listen to my own playlist. FFXIV is probably the only MMO I play with the sound on.
