An interesting thing about purchasing through MusicMatch, I can only make three copies of a song or cd. Now I haven't lost a cd yet, but I can see where that could become a pain.
In any case, I've simply stopped purchasing music, in any format- it's not worth it and I don't need it. (I can conceive of a parallel to cigarette addiction and music addiction- in a strictly limited sense.)
I like being able to purchase songs from iTunes because I don't generally buy whole CDs. I'm willing to live with the DRM limitations since I can buy just the songs I want for 99 cents each. Yes I have been concerned about what happens if my hard drive becomes unrecoverable, but I don't have enough invested in downloaded songs that I even bother to back them up to CD/DVD.
