He came into music prominence in 2004 for producing Kelly Clarkson's single "Since U Been Gone" with Swedish record producer Max Martin. "My My My" is a song by producer/DJ Armand Van Helden.  The song contains a sample of the song "Comin' Apart" by Gary Wright.  The track was produced in 2004 and included on the album "Nympho".  It is also featured in the video game "Dance Dance Revolution Extreme 2" by Konami as a licensed track under the house music genre at 128 BPM.  An alternative version of "My My My" featuring the vocals of Tara McDonald was released in 2006 and became a hit single that year.

"There She Goes" is a song by English singer-songwriter Taio Cruz from his third studio album, "TY.O".
