Why are some of my music files not showing up for ringtone and notifacation?

[Android Central Question]

I have a Huawei sensa and I download some music off of google music. When I go to the ringtones and such some of the music don't show up.

Please help!

Ringtones have to be in a folder named Ringtones (upper-case R matters) - notifications have to be in a folder named Notifications, alarms in a folder named Alarms.
