Just in case someone is as lost as I was for hours, here is a tip.
I wanted to make a custom sound for my alarm clock, and kept thinking I'd put the mp3 in my notifications folder. This to no avail.
I finally caught the word "ringtone" on the page to set up the alarm.
After placing the mp3 in the ringtone folder, it worked.
Good luck to you all.
Mark.
