Wow - what a great thread! And what a great list! I think I agree with every bad song listed - they were all my favorite stupidest songs of all time, it seems, at one time or another! Two thoughts to add though;

Someone listed a Neal Diamond classic, and I'd have to go further to add just about any Neal Diamond song would make my trash list, at least if Neal is singing it.

But my nominee for the world's all time worst pop tune is the Pina Colada Song - you know the one where the guy's tired of his girlfriend - puts an ad in the paper for a romantic opportunity - and it is responded to by his girlfriend? This classic bad song had absurd lyrics, a childish point, incredibly unimaginitve melody, a bad arrangement, and was sung by an extremely limited singer. Seems to me this stinker's a hand on winner!
