Weird zap/beep sound sounds during playback

On this song (attached below) ,a weird,low beeping sound (sounds like a zap),sounds during playback.This happens randomly, it did this a few times in a row every time I played it until I started writing this,then it stopped.
Also,(more minor issue) the scrolling is funky, when you scroll, you start scrolling, then move to the top of the page,start scrolling go back to the top of the page again etc....., this only happens during playback.This only happens on the first page.
