I just discovered PeerTracks today and I'm very happy with my experience. I've been keeping an eye on MUSE since it was a DPoS coin and I was one of the first few users to join PeerTracks. So I love the bragging rights.

I made a post about PeerTracks and tried to answer some question as much as I can. Feel free to correct if 'I've made any mistakes: https://steemit.com/steemhunt/@vimukthi/music-streaming-on-blockchain-ad-free-and-based-on-the-same-technology-behind-steem

Are you going to add the ability to buy music on MUSE? That would be really great. Best of Luck!
