Play-button UI does not update correcly #1
Description
When pausing a song and then clicking the button to start the previous song, that song starts playing but the play button still shows the wrong icon.
When now clicking the play button, the song correctly pauses and the play button changes its icon but now again has the wrong one, so the icon is the oppisite of what it is supposed to be until the playlist is stopped and started again.
This is because the 'prevoius song' button always starts the song without accounting for the state of the play/pause button
