A song can take many forms and meanings, depending on who's listening to it and at which point in their lives they are. We all have our interpretations, but I'm always curious to know what the artist's inspiration was, to get a better feel for where they were coming from. That's why I often find myself reading Spotify's Behind the Lyrics cards whenever I come across them. But the music streaming service seems to be adding its in-house spin that doesn't rely on third-party service Genius, by providing artists with a new Storyline feature.
