Your cheatin heart will tell on you...

This song is about fidelity, as Bono sings of how he would not jeopardize love for romance elsewhere. It's not a common theme in Rock lyrics, as in many songs the singer refuses to limit himself to one woman.

This song tells the story of a woman ending her relationship with a gentleman, who dated her, after catching him cheating on her with another girl. The woman tells the gentleman to go get another dumb blonde because he wasn't going to be with her anymore.

This song is about revenge. Underwood sings about going into a parking lot and vandalizing her cheating boyfriend's 4x4 truck with a baseball bat. She finds solace knowing that the next time he cheats, it won't be on her.

On this song Carey threatens to out a cheating lover on national television. The song's subject matter of revenge is a topic Carey has rarely tackled before.

This one is about a girl - the girl Marcy Playground lead singer John Wozniak had an affair with. The girl that came between him and Raine, the woman he would later marry. In our interview with John Wozniak, he explained: "We broke up because I had a relationship with another girl. Yeah, I cheated on Raine. And this other girl turned out to be the biggest mistake of my life. But I thought I was in love at the time. And I was wrong. I just really was infatuated, is what it was. And Raine took me back after some time. (laughing) After a lot of penance paid. Yeah, and I wrote that song about that. 'Blackbird' is, as my mom would call her, 'the girl with the dancing eyes.' That's what my mother would say."

On an interview on XM Radio, lead singer Sully Erna talked about his fame and how he cheated on his girlfriend for many years while the band was touring. She decided to stay with him, but it seemed like she would bring the cheating up whenever they had an argument. The song is about him saying, "I have screwed up and I have paid for it but you continue to bleed the life from me when you bring the subject up." He gave her credit during the interview, saying that it was a huge pill for her to swallow and he appreciates her for that.

In an interview with the Christmas 2009 issue of THE BIG ISSUE, Michael said of this song, "I'm still a bit puzzled why it's made such an impression on people... Is it because so many people have cheated on their partners? Is that why they connect with it? I have no idea, but it's ironic that this song - which has come to define me in some way - should have been written right at the beginning of my career when I was still so young. I was only 17 and didn't really know much about anything - and certainly nothing much about relationships."
It would later reach number one in more than 25 countries and sell in excess of six million copies worldwide.

Adele explained to the Sun newspaper January 18, 2008 about this Mark Ronson collaboration: "It's about being cheated on. Wishing you were the other girl. I love the tune. I've loved Mark since his first album Here Comes The Fuzz. But I didn't know he'd got into producing for other people. Then when Amy's (Winehouse) record and Lily Allen's 'Littlest Things ' came out, I remembered hearing about his covers album. I wrote my song 'Cold Shoulder' and my label XL were really keen to keep it how it was. But I thought it needed a beat because the album was lacking a real upbeat club tune. And I couldn't think of anyone else but Mark Ronson to do it.

This was a continuation of a song "Confessions Part I," which describes a one night stand. In this song Usher now has to admit to his girlfriend that the lady he cheated with has just told him she's pregnant. "Confessions Part I" was ultimately left off the Confessions album, though it's included on its special edition release.

This is about a woman who is not happy with her man, so she sneaks around ("Creeps") and cheats on him.

Justin wrote this about Britney Spears. In the song, the relationship goes bad because the girl cheated, and to get even, the boy makes sure that the girl finds out he's moved on with his life. The girl gets upset, and "cries a river" because she screwed up and lost the boy forever.

The song is about a guy who gets caught cheating on his girl, but denies it even though he is clearly guilty. It was inspired by a comedy routine Eddie Murphy performed in his movie Raw. Murphy said that no matter what your girl accuses you of, never admit to anything, just say "It Wasn't Me."

In this song, the singer goes crazy when she finds out her husband has been cheating on her. For most of the song, she seems to accept the cheating, but she ends up throwing him out of the house.

Before REO Speedwagon recorded this, they were known as a hard rock band. Keyboardist Neal Doughty initially had concerns about recording this love ballad, but his fears were allayed when this proved to be a breakthrough hit for the band. He recalled to Noisecreep in a 2011 interview: "During the making of the Hi Infidelity album, most of REO Speedwagon was going through some kind of personal turmoil. I'm talking about divorces and all sorts of crazy stuff. I remember when Kevin played me 'Keep on Loving You' for the first time I was a bit apprehensive about recording it. You have to remember, up to that point we were known as a rock band and here was this soft song.

This song is about a woman who cheats on her husband. She is very confused and down, and tells her husband she is going to see a friend when she is actually going to meet her lover. She goes across town to meet the boy with "Fiery eyes and dreams no one can steal." She gets there and she falls into his arms, but has to leave to go back home. She swears someday she will come back forever, because she is happy there. As the song continues, she ponders her emotions - "She wonders, how it ever got this crazy..." She just wants to feel loved and happy but she is torn.

The song seems to deal with cheating, as evidenced by the video, where everyone has fish tanks surrounding their heads. We see a girl walking down the street who notices a stray fish (representing a boy). She picks it up and puts it in her tank (representing sleeping with a boy). Her boyfriend finds out and dies. She discovers him, and does the same. The ambulance team, played by the band, puts them in the water, where they are reincarnated, never to surface again.

Killers guitarist Dave Keuning wrote this about lead signer Brandon Flowers' ex-girlfriend who cheated on him. Flowers recalled to Q magazine March 2009 how he discovered her with another man at the Crown and Anchor pub in his hometown of Las Vegas: "I was asleep and I knew something was wrong. I have these instincts. I went to the Crown and Anchor and my girlfriend was there with another guy." Flowers added that the song was "born" at the Crown and Anchor.

This song is about a man who comes home to see his wife in bed with another man. He starts outside the house watching until he builds up so much rage that he sneaks into the house and up to the room. The character then confronts the two in the act and (many explicative words later) decides to kill them one at a time while the other watches. The man then turns the gun on himself. The lead singer Justin Furstenfeld said that this is the song that gave the album a parental advisory sticker.

This song is about a woman who is cheating on her man, and realizes that he knows. She starts to regret the affair because of what it's doing to him.

In this song, a guy comes home to find his wife cheating on him with another man, so he takes out a gun and kills the guy. He feels no remorse for his actions, and seems quite relieved as his problem is solved and he has taught his girlfriend a lesson.
