WTF - Songs about Cheating

I was home on Wednesday doing my usual cleaning.  I was working on folding clothes in my room when the wife decided to come in and talk to me.  I usually listen to music while working at home to help pass the time.  I don't remember what song was playing.  The wife made the comment "Why is it that most of the songs you listen to are about cheating?"  I just looked at her.  WTF?  What in the blue hell are you talking about?  Most of what I listen to is old R&B.  Baby-making music as some like to call it.  Now every now and then I will listen to something about infidelity but not all the time.  More importantly, it's just music.  It's not how I live my life.  I need her to stop being so paranoid.
