"Confessions of a Broken Heart (Daughter to Father)" and "Speed of Sound" were both released in 2005, but 6 months apart from each other ("Confessions" on October 18, "Speed of Sound" on April 18). "Confessions" is in the key of G-Sharp Minor and at a tempo of 120 BPM, whereas "Speed of Sound" is in the key of A Mixolydian and at a tempo of 123 BPM.
Bruno Mars' single Treasure (released May 10, 2013) bears some resemblance to Breakbot's Baby I'm Yours (released February 25, 2010). Similarities include: chord changes/progression (though the song keys are a whole step apart), BPM (116 vs 118), and production/arrangement. Also, check out George Duke's Reach Out, or Kool and the Gang's Steppin' Out and Take it to the Top for very similar vibes/production. [Thanks to Andrew Zucker for this comparison.]
