Here's a thought. Rip your own mp3s. For stuff not already in my collection I buy it, unless I find it in a friends collection. Then we arrange a mutual backup protection scheme wherein I keep copies of the friends data (music) and the friend keeps copies of mine. We own the right to a copy of the music and have the right to protect that copy. We are not sharing the music, oh no, that would be illegal. Though we do swap music often, just the same as if we borrowed each others CD's.
I use a free program called CDEX that does a great job of ripping at high quality. Better mp3s than you can download for sure.
