Anyone and everyone seems to be adding music capabilities to their services, whether they make sense or, as in some cases, not (hello, LINE). The latest to join the fray is Vine, but don't be afraid, this isn't a new music streaming service. Considering Vine's nature of looping videos (do I hear GIFs?), "Music on Vine" takes on a different meaning, which is to say, looping sound clips. While that has always been possible to do manually, the new Snap to Beat tool makes its, well, a snap.
