Most annoying song, period.

Sorry if I'm replicating a thread.    I've been wanting to say this for years:  Rick Astley - Never gonna give you up.  What's yours?
Dust in the Wind. Kansas

I literally will leap tall buildings to change the station.
Free Bird - Lynyrd Skynrd

As a retired musician, someone at every southern outpost was guaranteed to scream this ‘request’ at least a dozen times a night. Whenever I hear that opening slide, I feel like I’m getting a kidney stone.
I agree with Eric,  Feliz Navidad is the worst song ever followed closely by Honey by Bobby Goldsboro.
That Xmas song by McCartney is pretty annoying too.  I'm surprised it got a few votes here.   For years, I used to think some wannabe Brady Bunch band sang it.  That's how bad I thought it was and still think it is horrible, though I do love the Beatles.
