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?
Here's a couple stinkers nobody mentioned;  "Puff the Magic Dragon" and "Leavin' on a Jet Plane".  Peter Paul,and Mary. Wasn't Peter a pervert? Or was it Paul?

I'm always surprised when I hear 'Blister in the Sun' at MLB games.  
@Mitchagain, I've never heard that!  But i laffed my ass off when I read your reply!  It sure is ghastly!
