Sleep timer that shuts app off after your queue

[R3DNAX_]

For now,the options for the sleep timer are: 5 mins, 10 mins, 15 mins, 30 mins, 45 mins, 1 hour and at the end of the currently playing track. I think it would be a good idea to add an option that will shut off the music after your queue. 

Thanks for the opportunity of giving you ideas. I hope to see any updates regarding this small feature.
