The problem is you have CDs 'your borrowed' from friend or CDs you 'sold at a carboot'. No disrespect but in both instances that is a breach of UK copyright law.

The music industry turns a blind eye to the fact that you buy a CD, burn it onto your PC and IPod, but to then sell the CD on means you have no further 'right' to play the music. Similarly borrowing and copying a CD is a breach of the law.

It really would be against this forum's rules surely to advise someone how to breach copyright any further?
