What I mean is as the song plays, the album art slides to the left, being replaced by the album art of the next song. Once the next song's album art is completely visible, that's when the next song starts. You could then do away with the seekbar completely.
Ok, so I thought that you could integrate the time bar with the cover art, and have the cover art slide to the left, with the next one being right there flush with the first one, so the cover art would kind of flow between the songs. It wouldn't be ideal for listening to whole albums, where the cover art is the same, but for playlists and individual songs, I think it might be cool
