This extension is a client-side music player. It gathers all the links in a webpage and opens a media player with the musics (.mp3, .ogg, .flac, .m4a, etc.).
It works great with open directories. If you want to find open directories with musics, head this way : https://www.reddit.com/r/opendirectories
or use the integrated search box.
