This is a small tool for the OBS Browser Source, meant to play music on a stream, and show the name of the new track and its author as songs change in a small, temporary pop-up.
No external applications or OBS plug-ins are required for this to function. Your music is simply played by obs-music-display itself, via an HTMLAudioElement.
Therefore, this does not work with any streaming services, but I would not recommend playing copyrighted music on a stream anyway. You will need locally stored music, located in a music subfolder.
A web server is not required to serve index.html. The application is CORS-free and you can just point OBS directly to the file.
A playlist.txt file must be generated first. You can either run genplaylist.js for this via Node, or manually edit the provided sample file.
