MEGAUPLOAD – Final Fantasy XIII-2 Theme.m4a (http://www.megaupload.com/?d=M6TFSPRD)
It’s the musical theme that loops over and over on Square-Enix’s Japanese Final Fantasy XIII-2 website [http://web.square-enix.co.jp/fabula/ff13-2/]. Someone on finalfantasy-xiii.net (http://finalfantasy-xiii.net/forums/showthread.php?t=14315) was able to encode it as an AAC (m4a) file.
