So you posted your music on bandcamp, good. So your charging money for it? BAD, and here’s why. I think I can speak for the majority of the consumer market when I say “I’m poor!”. Free distribution is the life force behind the growing Bedroom Artists scene because let’s face it, you’re one in a million. You may be the best in that 1/1,000,000 but in the end that’s subjective, isn’t it? So you have two choices: You can let me have your music for free, earning my eternal respect and gaining a fan who will one day pay to see you live or you can charge me money, in which case I wont buy it, wont become a fan, and wont show up to your live show. Not because I want it that way (truly I’d love to pay you all for your hardwork) but because I gotta eat and pay rent. The money will come, so just chill.
PS: charging for an MP3 is like charging for a deskjet printed copy of the Mona Lisa.
