Spotify / Musixmatch
Spotify will make your singalongs a better experience. It's rolling out its synchronized song lyrics to all users worldwide. The company started testing this feature out in the US and a few markets, but now free and Premium users are getting access to lyrics for the "majority" of Spotify tracks. Musixmatch powers the experience within the app.
It'll be available on iOS, Android, desktop, TV, and console apps. The feature is accessible on the "Now Playing View." You just need to swipe up from the bottom of the screen. The lyrics will track in real-time. Spotify hasn't mentioned how many songs get the feature, but saying "majority" implies it's at least more than half. We haven't spotted it on our devices yet, but we're keeping our eyes peeled for it.
