Hive account@prc best wishes from @LetItPlay team to DSound!
I'm CEO of LetItPlay - audio layer of the Internet. We are working on number of products similar to yours. Our products is still centralized but we are going to implement advanced attention economy on blockchain soon. So we are choosing between two blockchain cores: SMT.Steem and EOS. It would be a good decision for our projects to collaborate on this task. If you are intrested in collaboration - lets talk about common blockchain.
