I appreciate that the site is still in beta, but I don't think any of this stuff is particularly difficult.
1/ Fix the player. Fix the damn player. About a third of the time—and especially if you're not on Chrome on Mac OS—the track won't play. It's such an embarrassment. "Hey, friend, you should check out this new music site, yeah, it's based on the blockchain, they're paying musicians over 10x better royalties than Spotify, yeah, it's awesome", and then they go on Musicoin, and the player doesn't work. Fucking cringe. I know that there is complexity here, in that the web interface has to update the blockchain, which Spotify and Soundcloud don't have to do, but at least for verified artists you could load the music automatically and use a buffer for updating the blockchain? After all, they're going to get a credit from UBI regardless of whether or not the listener has balance.
2/ Playlists. I saw a tweet from the official account a couple of weeks ago that suggested this might be a paid functionality? Yeah, good luck with that. This is a very, very basic functionality on Apple Music, Spotify, and Soundcloud. Which listeners are going to switch from that without playlist functionality? Almost none.
3/ Allow downloadable purchases. This will strongly incentivize non-musicians and non-investors to buy Musicoin. Hey, you can listen to this track for free on UBI.... or for x amount of credits (say, a fixed number of Musicoin, or a fixed dollar equivalent) you can download the tracks in lossless quality. Boom, people are going to come in. Instantly creates a market and boosts the coin.
Anyway, I love the project, keep up the good work, and implement this stuff.
