When I saw the thread title, my first reaction was the same as Whistle Stop's: what the singer has been is "downhearted," not "down harder," as expressed in the opening line of BB King's very-well-known "How Blue Can You Get."

An obvious "mondegreen."

After opening and actually reading the thread, I learn that things are more complicated than that. It would seem that a group of white punks on dope (presumably ~ I know nothing about the Primitive Radio Gods and never heard, or heard of, their song) misheard the original lyric and then built a whole new song around the altered phrase. Interesting ~ a whole new avenue for inspiration in songwriting!
