I don't think you're familiar with MySpace then if you find this odd. MySpace/Artists are always doing "First Listens" on there. Heck, Potluck did one back in... January(?) for their album.
i dont think its retarded.....they're doing it to combat the album leaking....Its easier for mutha fuccaz to just go listen to it on their myspace than to take the time to download it and shit.....Im pretty sure Eminem did tha same fuccin thing only problem was his album leaked before it went up on myspace....
