Android :: Ringtones Notification And Alarm Ringtones Randomly Changing

The reason I KNOW its not me changing these ringtones in all of the assignable designations for media files to be played for the ringtones and such is that I have not a single of my music files within any of these settings as an option to assign in the first place. They are showing up randomly. This morning I awoke to Rock n Roll by Led Zeppelin, and earlier today a friend called my whose ringtone was changed to 99 Red Balloons.
Let me reitterate; I have never assingned a music track as a ringtone, alarm, or notification. The previous ringtone still exists in my library and is functional IE; i can reassign the same ringtone to a person again. I THINK that only ringtones which are NOT DEFAULT are changing. What is going on here? I have lookout AVP app loaded and running at all times.List on my runnng apps on EVO:

I do have an abundance of navigation (gps, turn by turn, ect), some news, a widget for quick settings (wifi, bluetooth, ringer on/off, gps), Music (shazam, pandora tunee music, The house FM christian radio) Astro file manager, Emulators, facebook integration.I have noticed some coming on by themselves. Ill try to note when I have done nothing to activate them.
