Vine is getting into music. With an update rolling out Friday, Vine will begin letting its users add music to their videos. The music will be selected and licensed by Vine — it’s not yet clear whether you’ll be able to dig into your private library to put “Bad Blood” over everything. Instead, after shooting a video, you’ll be able to look through a selection of tracks that Vine has picked out. You can place a song over your clip however you’d like, but Vine is hoping that you’ll use a feature it’s made called “Snap to Beat,” which will trim the music and video to the audio loop as perfectly as possible.
