Square Enix has launched Square Enix Audio. Square Enix Audio is a free music streaming service split in to channels for each game. Currently, titles include games like Xenogears, Drakengard, Final Fantasy 13, Sengoku IXA, SaGA and El Shaddai. The site's mostly in Japanese for now, but it's easy enough to navigate. All you've got to do is select a game and you'll be able to listen to music from its soundtrack, buy the songs, and tell your friends what you're listening to via their social media integration. I listened to some Xenogears while I wrote this post. Memories!
Once they add new games to the service (like Chrono Cross, because it has the best soundtrack ever), and translate it to English, I can totally see myself listening to Square Enix Audio all the time while at work. What about you?
