After pushing out updates that focus on making its visuals better, Vine (for iOS and Android) is getting a major upgrade that introduces a bunch of new music features. The one that sounds most useful for creators, especially if you need a bit of help to quickly edit tracks for posting, is "Snap to Beat." Once you switch it on, the app can find the perfect part of the song to create a never-ending music loop with. You can, however, disable it anytime to add sound effects or to customize your BGM. In case you want to use a popular song, though, just click the app's music note icon to access a new scrollable Featured Tracks section full of well-known singles you can add straight to your six-second videos.
