On Again/Off Again Relationships

Will you or won't you share a song for the Question of the Day? One day you will, the next you won't. It's kinda like an on again/off again relationship. Songs about those ambivalent relationships are what we want. Or are they? 

Hear your requests weekdays after 9 a.m.
Today's set:

• The Ronettes "(The Best Part Of) Breakin' Up"
• The Ting Tings "Shut Up and Let Me Go"
• Courtney Barnett "Pedestrian at Best"
• Stevie Nicks with Tom Petty "Stop Draggin' My Heart Around"
