Kelly Clarkson "Already Gone"

Remember the great Feud of 2009? Of course you don't, but here's what you forgot didn't care about what happened during August 2009. Just before releasing "Already Gone", Kelly Clarkson wanted to shelve the ballad because she thought it sounded too similar to Beyonce's "Halo". Before joining Clarkson to co-write "Already Gone", Ryan Tedder worked with Beyonce on her I Am...Sasha Fierce album. One quick listen and you'd pick up notable similarities in "Halo" and "Already Gone": hand claps, mellow piano, and the drum rhythm. Clarkson didn't want to be accused of ripping off Miss Sasha Fierce and wanted to ditch the single. Her record company released it anyway and she blasted them and even ripped Tedder (who defended himself on Myspace -- remember that?). In the end, "Already Gone" went to #13 on the Hot 100 (#3 on Adult Contemporary) and finished #1 and #5 on the Adult Top 40 and Mainstream Top 40, respectfully. Tedder, you may recall, also went on to fame with One Republic. I think everything worked out just fine.

Pink "Who Knew"

Credit Pink for ripping Kanye West a new one during his infamous MTV Video Music Awards spectacle in 2009. I know, it's hard to believe it's been a decade since a drunken Kanye stole Taylor Swift's moment. Kanye allegedly carried a bottle of Hennessey on the red carpet and that didn't do him any favors a few hours later when Taylor won "Best Female Video". Kanye charged the stage, stole Taylor's moment and the audience gasped. Swift cried, Beyonce cried, Kanye was ejected from the awards show, and eventually the world moved on...but not before a visibly angry Pink got in Kanye's face and shared a few choice words. Later that evening, Pink tweeted out that "Kanye is the biggest piece of shit on earth." Have a great day.

Anita Baker "Sweet Love"

Beyonce performed Anita Baker's ballad "Sweet Love" during a medley in a 2009 Vegas concert to promote her I Am...Sasha Fierce album.
