"Walk Away" is a hit single by the Dropkick Murphys. It was on their hit album Blackout in 2003. It's about the growing divorce rate in America. A man get's married thinking he's got everything figured out. But his greed and selfishness get in the way and his wife is adding to his stress. So instead of having the heart to finish what he started he either divorces her or simply "walks away" although walking away could simply be representing a divorce. The rest of the family falls apart and he leaves behind the one's he loved.
