We've been so busy with the Cold Sleep, we forgot about one of the most important releases in Perfume history, beginning a chain of events that eventually lead to Perfume's breakout and success.

The album "~Complete Best~" was believed by many fans to be Perfume's last release before Tokuma Japan would drop them from their label, effectively ending their career. The album actually sold better than expected, which prompted Tokuma Japan to give them one last try, and they release "Fan Service: Sweet" on February 14, 2007. Jpop/rock star Kaela Kimura came across "Chocolate Disco" PV from the "Fan Service: Sweet" CD while shopping in a department store and fell in love with the group. She began playing the song on her weekly radio program and that caught the attention of Akira Tomotsugi, a commercial director for the NHK television network. He then hired them to do a song for their National Recycling Campaign and appear in the ads. The song was "Polyrhythm," and the CD was released September 12, 2007. It peaked at number 7 on the Oricon charts.

Here, the members of Perfume talk about how Nakata lost the master recording of the song. Midway, Nocchi (I believe) starts humming the tune. Apparently, the three ladies received a copy of the song on CD before it was accidentally deleted. So copies of the song still exist.
