Galbadia Hotel is a great site for both Anime and Game music. It should be up eventually again once they get some funds from donations.
Isn't that site the same site where it lets you download the music for free? I rather buy my soundtracks, I'm not a fan of downloading music when it's on the market... that would just be stealing. Another site like that is Bluelaguna.net, which I use to listen to a RPG soundtrack first to decide whether to purchase it or not. Thanks for the suggestion, appreciated just as much.
