LG Rumor Touch "My Audio"?

[youknowme]

So I've noticed when setting ringtones for specific people or for text messages it gives you options of where to get the ringtone from such as: Downloaded Ringtones, Other Ringers, No Ringers, Voice Memo, and MY AUDIO.What I am wanting to do is get a specific clip of a song into the MY AUDIO section. I've put it on my micro SD card under "My Sounds", "My Music" and other areas even created a folder called "My Audio" and it still does not show up in the My Audio file when going to add the ringtone to my texttone. If anyone knows how to get it to the My Audio section please let me know. Thank You
