I agree mostly with their comment.
What I want more than anything is for bands to just sell me a damned CD. I've lost track of how many times an artist I want to support doesn't release their music on CD. I'd even settle for DRM-free flacs, if it costs less than a CD.
High quality sheet music would be cool. Lindsey Stirling is the only artist I can think of that does that though. Rasputina used to at one point.
