There's an industry move towards dropping DRM...

I think we'll see this eventually. I refuse to purchase music from Puretracks. When I bought a new computer, I had difficulty transfering tracks purchased via Puretracks because the DRM wouldn't transfer with the file. Tracks I purchased through Napster were fine.
I subscribed to e-music for about a month. I found the selection was poor. Maybe it will get better.
