This is a fan-made compilation of final boss music from many different Final Fantasy soundtracks. These are not re-arrangements or remixes. If you want to have all the Final Fantasy final boss themes (or at least all of them for the games released so far) in one place, this is that place! As the quality of each track depends on its original soundtrack, I can't guarantee MP3 320 for all of them. I don't have a FLAC version either.

I hope you enjoy!

EDIT: version 2!

Changes:

Replaced Final Fantasy X's final battle theme with the HD version from the PS3/Vita remaster
Added final battle themes for Lightning Returns: Final Fantasy XIII and for Final Fantasy XIV: A Realm Reborn

Note that there is no official name for the final battle track for Final Fantasy XIV: A Realm Reborn yet. The current name ("Lahabrea Battle") is a placeholder.

Ooooh, nice. Thanks a lot!

Updated first post with a new link and a changelog. Added two tracks, also replaced one other track.
