Turntablist mix/compilation CD help needed
 

Okay, so I actually found someone who's interested in my DJ music and I'd like to put together a mix CD. When I began organizing the songs, I put them into three categories: Fast, Mellow (or rather, not as fast), and hip hop dj.

My first inclination was to make three discs, each based on one of these categories. Now I'm not so sure.

So, should I make three theme discs or just use a complete mix? I'm not even sure which I'd like more...a disc with similar sounds, or one with a changing tempo.
