Is software free trial similar to this? Don't we, as developers, give our software for free in either a freemium or free trial business models? One freemium tool I'm involved in only monetizes 2-3% of our users... But it's a model that works as far as marketing goes.. Not saying you shouldn't pay artists but isn't this another form of marketing to users? In the end, it's win-win. Apple gets more users, artists gets more listens...
