Chose the time you'd like to set it for! I'd recommend to fullscreen it, but it doesn't matter. Press the golden button to change the background color. The music symbol controls the music. Press it and it'll play a song. Press it the second time and it'll play a different one. Press it a third time and there you have your third song to play. It is not automatic, so if the song ends, click it again to play the next song. Enjoy! This was a timer made for one of my classes. :) Happy Holidays people. All coding by me. Pentatonix for the songs Carol of the Bells, The First Noel, and Angels We Have Heard On High
