'Fall for You'
'Fall For You' -- featured in the album, 'A Twist in My Story' -- is about a love-hate relationship: "Tonight will be the night / That I will fall for you over again / Don't make me change my mind." John Vesely, solo project for Secondhand Serenade, performs the song on piano, which was helmed by songwriter-producer Butch Walker.
'Hot N Cold'
'Hot N Cold' was a follow up to Katy's hit single, 'I Kissed a Girl.' Obsessing over the hot and cold nature of her relationship, she sings: "You're yes then you're no / You're in then you're out / You're up and then you're down / You're wrong when it's right / It's black and it's white / We fight, we break up / We kiss, we make up." The contrast in the song must have worked -- the single was a major hit in 25 countries!
'Let It Rock'
Pink puts her private life on the table in this catchy 2008 song ("So what / I'm still a rock star / I got my rock moves and I don't need you"), even featuring her husband (then separated) and motocross racer Carey Hart in the hilarious music video. A few months after the video debuted, Pink and Hart got back together.
'Take a Bow'
'Take a Bow' is off her 2007 album 'Good Girl Gone Bad.' The Ne-Yo-penned ballad has Rihanna singing about how a relationship is over: "And don't tell me you're sorry 'cause you're not / Baby when I know you're only sorry you got caught / But you put on quite a show / Really had me going / But now it's time to go." The music video showcases just that, with Rihanna tossing her boyfriend out of her life after she finds out he cheated on her.
'Viva la Vida'
Musician Joe Satriani accused Coldplay of copyright infringement, saying that Coldplay's repeated, punchy string section, or melody, was copied from his 2004 'If I Could Fly.' Just months after both parties reached a financial settlement, 'Viva la Vida' won Grammy Awards for Song of the Year and Best Pop Performance by a Duo or a Group.
'Just Dance' is about being wasted at a night club: "What's going on on the floor? / I love this record baby but I can't see straight anymore." The song was in the Billboard 100 for five months before it topped the charts in January of 2009.
Every girl wants this love story: "Romeo, take me somewhere we can be alone / I'll be waiting, all that's left to do is run / You be the prince, and I'll be the princess / It's a love story, baby, just say, 'yes'." The 2008 song was one of the most downloaded country tracks in history, heavily due to it's cross over from country to pop.
