Achy Breaky Heart was the first song that popped into my head when I saw the title of this thread. But we've had some real crap: all yacht rock (probably should be called yacht pop, since "rock" it is not), Christopher Cross, Air Supply, Barry Manilow (not everything though -- I like "Mandy" and "I am Music, I write the songs" -- but "Copa Cobana"...? Please make it stop.), the Richie Family, Stars on 45, etc.
