When I burn mp3's generally my music. I can hold roughly around 150ish songs. Before I started burning music, the mp3 I looked at of my friends had around like 300ish. Is there someway to condense the data or do they use different type of cd's?
It depends upon the bitrate at which the mp3 is encoded. The higher the quality, the fewer the number mp3s that you can fit on a cd.
