Well...
If the same songs were released as a general compilation, would you rush out and buy it?
Just cos it's got the Moz seal of approval, doesn't mean I should part with my cash. I bet most of the people on here had barely heard of the artists featured. I know I hadn't so I'd rather hear a few tunes from it and then if I like what I hear, then I would buy it.
The fact that it is only available on CD is a bit of a pisser. Can't stand the things. They're good for copying music, but for album originals, you can't beat vinyl.
