Show HN: Disco.io – A personal streaming music library (disco.io)

I use Disco weekly as a much friendlier and more fluid alternative to YouTube playlists or Chrome bookmarks for songs that are so new they aren't on Beats yet. I can't wait for the mobile version, especially if it'll offer continuous background playback. I haven't seen that done for YouTube videos on mobile anywhere yet.

We are currently sending invites in near real time.

I feel like there are already so many services like this!
