Hello,
Sorry so late with getting back to you, but good news. I resynced my usb with my computer, took out my USB drive from my head unit, did full rescan in Poweramp, remounted usb, and rescanned. Solved all issues embarrassingly simple LOL. I think you were right... I think it attempted to rescan before when the drive wasnt mounted. Its been a little touchy lately and not sure why. Thanks for your help though!!!!!! :):)
