do you think it's possible including a CD-R will increase sales significantly, though? I'm thinking of an average showgoer who listens to his iPod a lot, sees the record, thinks "that's cool", but doesn't own a record player or, at the very least, probably doesn't have digitizing capability attached to it. so instead of buying the record he'll dl the songs from a torrent site or soulseek or something.
whereas including a CD-R would enable him to make that purchase from you. the songs WILL show up online and unless you are a huge, deep, collector-minded fan of the band, you're unlikely to buy a record you can't comfortably listen to when you can get the songs for free online.
