When I close the application after using it all day, I usually have a few songs open.
For each song that closes when closing S1, I have to wait about 10-15 seconds for each song to save, then I am prompted whether I want to Save the next one.
This is unnecessarily time consuming and annoying as I have to sit there and wait to close each track.
Please add a option to "save all" or "do this for other songs".
