For reasons known only to themselves, Spotify recently removed the rewind (or 'go back a track') button from their app. How are we supposed to listen to 'This Song's Gonna Get Stuck Inside Your Head' over and over without it?
(Yes, OK, the loop button, but then we'd have to make a playlist with just that on it and EFFORT).
Apparently Spotify heard everyone's complaints about this and is bringing the button back to the app. If you're using Desktop Spotify then you're fine, it never disappeared in the first place.
According to Techradar, the return of Rewind comes with some small interface changes: namely a heart button for saving the track to your favourites, and left alignment for artist names and song titles. Nothing major.
If you need a rewind-worthy playlist, Spotify's Girl Power Throwback Thursday effort for International Women's Day is absolutely banging.
