This is the newest disc in the market today, most of this disc are used in PS3 console. Have anyone used BD in playing music? With an average of 20 GB of capacity, your whole library of MP3 will fit in there.

I have heard about these kind of CD's. Can they be used in digital DJing? I think they need a different kind of digital turn table to be able to play them. If what you say is true then a whole night of partying is not enough for a 20GB of pure music.
