Uh, 'official' you say? Those 'albums' you quoted don't actually exist, as there is actually no official soundtrack album available for ARR yet, other than the small 6-track mini-album Sounds of Eorzea that came with the Collector's Edition. There is also the complete 1.0 OST Before Meteor which has a lot of tracks that were reused in ARR, and three earlier albums for 1.0 that were only small selections (Field Tracks, Battle Tracks and Eorzean Frontiers).

Anything else is an illegal rip from the game, which sounds to me is what you've found and which has been passed off as officially licensed by SE when it's not.
