As a song plays, you're presented with a text window on screen that serves up more info on the song's lyrics as the music plays. We're talking things like tweets, info from producers and explanations of specific references, for example. You know, the stuff you've seen if you've spent any time on Rap Genius. Spotify says that a second playlist offering details behind the words of "hits" will be available soon. I assume this will include a smattering of top 40 tunes because a video that demos the new feature includes the Selena Gomez track "Hands to Myself." The Behind the Lyrics playlists are only available on the service's iPhone app, though, and there's no word on when they might stream elsewhere.
