Brianlippey is it possible you have DONE songs enabled and you have not cleared DONE for a while so songs are being skipped, thats the only scenario i can think of, if so just go to HISTORY AND HIT RESET DONE .
DONE is very useful when performing but if you don't need this just go to settings and tubrn it off.
SETTINGS, GENERAL,USER INTERFACE, BEHAVIOUR, SHOW DONE MARKER, OFF
