Name That Lyric: Episode 241

We have no winner from last week!! Nobody recognized

"My sense of humanity has gone down the drain
  Behind every beautiful thing, there's been some kind of pain"

from "Not Dark Yet" by Bob Dylan. Onto this week's clue:

We've been through this such a long long time
Just tryin' to kill the pain, ooh yeah
But lovers always come and lovers always go
An' no one's really sure who's lettin' go today, walking away



Good luck, Dillweeds!!
