Hey Wayne, my favorite method for I unsticking a song from my head is to replace it with an equally sticky song that I like. The usual result is that the new song dislodges the first song, but doesn't stick as well. On the off chance the replacement song sticks as well as the first, I find another sticky song to dislodge it with. Once, I had to go through about 3 or 4 replacement songs before they finally quit staying stuck. My favorite go to song is White Rabbit by Egypt Central. After that, I have a few Nickelback, Shinedown, and Theory of a Deadman songs that work pretty well too.
