Takes old FF songs from soundtracks and they remake them with real instruments. pianos, some guitar, tons of different files from ALL different ff's. they're in need of contribution money. they arent funded by anyone.
i have every song they have available. some of the most adaptive interpritations i've ever seen of any game soundtrack.
once again, if this is common knowledge, i'm sorry for spamming.
but it's worth the risk. this site's amazing.
