The button, which sits between options to Like and message the page below an artist’s cover photo, plays music using whichever Facebook-connected streaming service a person uses most frequently. Users can play and pause a song with the button, but they have to visit the streaming service to skip to the next song or fast forward through a track.

The feature will help users sample music when they visit an artist page for the first time and could help make Facebook a go-to option for people looking for new music, similar to how many people used MySpace in its heyday. Streaming services will benefit from the traffic and artists will appreciate Facebook linking to legally licensed versions of their work. Page tab application companies like ReverbNation and BandPage could suffer, since one of the key features they offer is music players for artists’ Facebook pages.
