Facebook has announced two big changes regarding the way music can be used on the platform. Users will now be able to include music within personal videos and choose from a variety of songs for a new feature called Lip Sync Live.

As of March 9th, Facebook had clinched music licensing deals with all three major labels, and now users will begin to take advantage of that. The company is testing out options to let people include music from these catalogs (which includes millions of titles) within their personal videos. It plans on rolling out this capacity on a global level, although no exact time frame has been given.
