Nice work dude
Only problem i had with it was actually getting the music to play :/ for some reason it would get to the timer screen and nothing would play.
imo you should try to make a version of the sleep timer where we can just set the timer cuz i would much rather set my music THEN enter the program. because right now it doesn't look like you can choose a band and put it on shuffle and thats what i wanted. think you could make a simpler version like that without the music chooser thing until you can get all the bugs worked out?
imo the music chooser feature isn't that necessary if you think about it, because i doubt you'll get up and want to change the music again if your trying to fall asleep.
