One coin that I'm considering investing into pretty aggressive is Musicoin.

Musicoin

Musicoin is designed to support the creation, distribution and consumption of music in a cycle. The system uses a special algorithm to generate a currency called Musicoin ($MUSIC), as well as another algorithm to support automated contracts ("smart contracts") which enable musicians and consumers to exchange value in a frictionless environment. With a unique currency and a solid peer-2-peer (P2P) contract system, large scale transactions around music becomes possible.
