Music+DRM=Headache.

I think Radiohead had the right idea. Pay-what-you want is the wave of the future. It actually encourages people to buy albums again, because one of the reasons people buy CDs less is because they are freakin' EXPENSIVE.

Then there's the whole thing where if people want to do something (i.e. share/copy music) they WILL do it. You can't stop a determined programmer.

Just my two cents.
