Reload song on double click
One thing that used to exist in v1 that doesn't in 2 is when you double click on a song in the service it would reload the song. I use it when I have the screen blanked and I switch songs, but may have forgotten to switch backgrounds. Double clicking on the background switches the default background, but I have to switch to a different song and then switch back to get it to show up.
Small annoyance, but would be nice if it worked.
