Very nice, ran well in a VM on my home NAS.

I've always noodled about this marketplace idea where an optimization algorithm could match your interests and a dollar amount you can afford to let you rent/buy artist's music. The optimization would maximize the purchase of the differently valued music(analogus to the weighted knapsack problem but this could have multiple solutions, knapsack is a nice way of thinking about it logically, in reality implementation may be completely different) based only on your interests, like history and dollars u have. I am wondering how might one apply a distributed systems approach without having music pirated and shotgunned all across the internet? Like how would you quickly match a person to all the available music metadata? How would you model for interest matching if the music library is spread out across multiple nodes.

I would imagine a lot of people are ok with paying 5-10$ a month instead of 15-20$ for music they like from a set of artists they like.
