Finally figured out how to set ANY song as an alarm, a notification or a ringtone, after having hacked apart several songs to come up with crappy, crunchy-sounding files that had about a 30-second limit. Instead of selecting the tone using the native file system, just use ES File Explorer. Not necessary to put the tones in any specific folder, or anything. I finally have the original Final Fantasy Victory Fanfare as my Notification tone, the Opening Theme as my Ringtone, and the Prelude Theme as my Alarm. Sepatown.
