Public Enemy Release full single as mp4

Tom writes "public enemy - the hiphoppers that already tried to put a mp3 on their website and where kicked by their label for doing so - have released the single "swindlers lust" in full length on their website. not only the release itself, but also the content of the single is a major criticism of greed and corporatism in the music industry. it's in the new mp4 format which rivals cd in quality. there's also a bit of a rant about mp3/4 and the industry on the website. " These guys are definitely bucking the industry- I'm glad to see someone is trying to do it, but how can I play an MP4?
