DJ mix tapes tend to use samples of other artists' music, which is a violation of their copyrights. If you want to be legal, get a lawyer to help you get licensing to use the samples. DJ mix tapes are a copyright nightmare, and it does not matter if they are offered for sale or for free. If copyrighted material is infringed, there can still be up to $150,000 in statutory damages, even if the material is given away, rather than sold.
