Why not make your band-stalking tendencies legit? Let bands crash at your apartment when they pass through your town on tour! Better than the Van connects bands with fans for free room and board. Struggling bands aren’t much different than struggling post-grads, trying to fill their bellies and pay the bills where ever the next gig awaits them with a paycheck.
There is always talk about how much or how little a band makes off album sales and how you shouldn’t get your music illegally because artists need to get paid. But maybe the barter system will work in this situation. You many download a free song here or there for a band, but in exchange you give them some floorspace, an aerobed, sheets, and some bagels in the morning. I think that seems like a fair trade.
