I often use the swipe-down-gesture to return from a album cover view back to the playlist.
The problem is that swiping down isn't working if you're listening to a song with Genius.com annotations. Swiping down only changes the album cover to the annotations and backwards. To return to the playlist you have to touch the down-arrow on the top left.
Is there a way to change the display of the Genius-annotations to another gesture to make the app more easy-to-use?
