This is hardly mainstream, but it's not quite gaming music either. I stumbled upon an old post here on FFShrine that had uploads of Guitar Vader's music, but they were all victim to the demolition of MegaUpload. Guitar Vader made notable contributions to the Jet Set Radio series, and that's a major reason why people in our crowd are so fond of them. The download links and torrents for their work are all dead, and finding hard copies of their early works is damn near impossible. If anyone around here has any of their albums, remix albums, EP's, or Demo's, it would be awesome if we could share. I have a download for their first album (Die Happy!) right here (https://mega.nz/#!ThYWnSgS!1S0v6rim-Rpbz1kU2du5Amy0_vZR4mC8dZGLzeulg9E), so I'll throw my share into the pot.

If this is considered too far off-topic for the forum, that's fine. I figure it's worth trying ;3
