The Xenon organizez your music for you,
Full music tracks are in the music player,
while ringtones go under sounds to be used for your phone.
All playable sound files, whether music or ringtone, go under audio.
And sounds has a list of different things that use sounds, like ringtone, message tone, and alert tone.
So if you click on ringtone in sounds, your setting the sound for ringtone,
which goes the same for message tone.
As for setting rings for a contact, you either go into audio or access the contact itself.
Untill we get some drivers, there is nothing that can be done to change anything.
Hope I was helpfull
