It feels like half the stuff I hear at weddings could be considered inappropriate.

19. Love Will Tear Us Apart - Joy Division

Songs have credited love with many things over the years, but never tearing anybody apart. Joy Division's seminal classic seems to bemoan the death of a relationship due to a couple's priorities changing - rather than any actual physical dismemberment.

Sample Lyric:
"When routine bites hard
And ambitions are low
And the resentment rides high
But emotions wont grow"

Little Known Fact:
Joy Division were an influential and critically praised band, but didn't sell many records. Released in April, 1980 this song didn't chart. A month later, depressed over poor health and a broken marriage, lead singer Ian Curtis hanged himself. The single was re-released in June and became their first and only hit.
