I make dance music/ hard breakbeat as a serious hobby. A trick that some producers do is find examples of music that sounds really clear and crisp in terms of sound quality and mastering. Then they compare the music made by themselves with the sound quality of the professionally mastered music. By doing this you can dramatically improve the sound quality of your own productions. The problem is that all the well mastered music that I keep finding isn't in the same gender as the music I make. I did find a useful link posted below but most of the examples on there were pop n rock orientated. http://www.nautilusproaudio.com/commercial_cds.htm
