You've just answered a question of little relevance to the topic: "Would Kensai buy DRM-free music simply because it is (among other things) DRM-free."

I'm not sure, though, others feel the same way. Most consumers probably won't mind (care about) DRM issue. Some probably won't even share DRM-free stuff.

Anyway, the question was if DRM was good for the artist. The difference between software and music is that music is almost exclusively for personal use. Software vendors will allow pirated versions on the loose because it's a free sample they can capitalize on in enterprise environments later. But music doesn't work that way, and vendors will likely attack bootleggers as soon as they see them. So, musicians may feel that it hurts their reputation among the fans. From that perspective, DRM may hurt musicians. OTOH, there are probably musicians who care more about their profits than public relations. But still, I don't think that's gonna be a big issue since, as I said, most consumers don't even care about it.
