mini disc is expensive (last time I check is around 10 CAD) and it is not widely used.... my mp3 player is used only on singles, besides it is multipurpose so you can store virtually any data file in there ..... When the album comes out i either buy or burn and use a cd player to play the song. moreover,a cd disc can be used almost anywhere.... car.... stereo...dvd players..... for me MD is only for techies.
