Found a problem today, but I'm not quite sure the cause. The alarm didn't go off this morning, so I set it again and watched the screen. When the time changes, the snooze button flashes on and then off, and then nothing happens. I tried it again, same thing. I then tried it again, but with some different songs, and it worked for 5 out of the 6 songs I tried. I'll have to test it a few more times to look for anything common among the ones that don't work.
