What earworm songs are burrowing through your head today?

When the Beach Boys were all over the radio, I always welcomed their songs, usually humming along. I figured it was because they weren't whining about true loves hit by a train or teenage angst... plus they had so many car related songs.
Later, when I started hanging with musicians, I began to understand why they were so ear worm worthy, and how some were so ground breaking they were teaching the Beatles, et al, their trade.
