Radio Starz is produced by Stellar Records, the same people that do Pop Hits Monthly.
I have a few of their discs, and in my opinion there is only one disc I think is a stinker, the James Taylor Disc, I just don't like the sound of some of the songs.
The Pearl Jam disc should be a must have for any library. It's also one of most used discs at my show.
Also their discs are recorded much hotter than any other manufacturer.
