I just wanted to bring attention to an album artork bug on the music for Spotify. The music plays fine, and the album artwork shows up in the little square, but in the Now Playing section, the album artwork sometimes doesn't show up and only shows the music symbol in a grey circle instead of the artwork itself. I don't know if this is just me and my phone, or a widespread problem. Hopefully you guys can fix it.
As Matt mentioned, this bug will hopefully be fixed in the next version. Any news will be announced in this topic. ;)
