Tune.FM is an interesting new company. It compares to Wavlake and LNBeats. They also use a micropayment system based on a platform called Hedera Hash???
They use JAM Tokens for direct to musician payments from fans. They use gamification, social networking plus rewards.
This is worth reading. We have many similar ideas for TrueFans. i.e fans pay creators but also creators can pay fans.
