He returned from the U.S. in early 2007 and began working on a new experimental musical project. Balan performed the songs, which were a deviation from his prior material, in a falsetto voice. These shifts led him to decide to release the music under the stage name Crazy Loop, an alter ego that contrasted with his real personality. The musician described Crazy Loop as "funnier, crazier and more ironic" than himself and said, "I'm not like that really but part of Crazy Loop lives inside me." Balan officially launched Crazy Loop in October 2007 with new single "Crazy Loop (Mm Ma Ma)", which landed on the charts in Germany, Austria, Poland and Romania, as well as on European chart Euro Hot 200.
