I've been listening to this online radio station lately, and it kicks ass. All it plays is Final Fantasy music and music from other popular RPGs (and remixes too...many many remixes). They were down for a few days cause of some issues with the RIAA, but they're back up now and say that the RIAA and them made an agreement, and FF Radio will go on since it only plays music from Japan! Cool huh?
