Uh....no...I've used MP3s for alerts, SMS, etc.

I had the Metal Gear incoming codec sound for my SMS incoming ^_^

Edit : O_O!! I don't see the "my ringtones" folder that I used to do that with...

Edit 2: HA! Got it. My Device/Windows/Rings Just copy any mp3 file in there, then when you go to Settings/Sounds & Notifications, it should appear in the dropdown ring tone menu. (Be sure to close out the sounds & notifications tab before or after you add to get them show up.)
