Welcome to Version 3 of MusicPlayer!
Features
This version introduces tons of new features and moves to a completely web-based solution.
The intended way of using this MusicPlayer is through the paid, hosted version of it available at music.janishutz.com, which you can use without any prior setup.
You may also self-host the MusicPlayer, you can find a rough rundown on the project's wiki page here on GitHub.
