Refrain: Collaborative playlists in Slack
Refrain is an open source, host-it-yourself clone of Jukebot, a popular Slack app. It allows you to share your Spotify account with your office and your taste in music with one another, for better or for worse.
Differing from Jukebot, Refrain gives communal control of playlist and user configuration. This means that you don’t have to rely on always having access to a single given Spotify account, and that you can listen to different playlists without giving up the ability to veto that one track you really don’t like.
