Punk Not Profit is one of many music download blogs that cater to the completionist in us all. I bet you thought you had every single inch of tape ever blessed (cursed?) with Glenn Danzig's voice. Is it important to have the instrumental outtakes from Samhain's November Coming Fire? I'm not sure, but there are worse compulsions out there.
Blogs like this help to bolster the argument that free music downloading drives the careers of musicians. Most of what Punk Not Profit shares is not available for sale anyplace anymore. I go on, download some rare bit of nonsense and keep scrolling. "Oh, look. An early Exploited demo. I've heard these guys are fun." Download. Listen. Buy some more music next time I'm in a record store. It's free advertising.
And if you prefer classic and psychedelic rock over punk, take a gander at The Day After the Sabbath. The dude loves you so much, he makes you a mix tape every few weeks. Then you start hunting down complete albums.
