Gar, the problem is with the drum note heard during the song's first measure count-off. During the count off it's 'in time', but immediately after that (:05-:06 sec) it starts up again but at an entirely different 'tempo & groove' and completely out of sync with the song itself, and continues (tick tick tick tick tick tick) throughout the entire song! I suspect now you had your keyboard's metronome 'turned on' and had it playing at a different tempo while recording and accidentally recorded that 'metronome tick' too. Whatever it is, I had a few other pro musician friends listen & they clearly hear it too. - Scott
