French superproducer David Guetta was forced to ask European radio stations to pull his collaboration with Rihanna from the airwaves, because the superstar had too many songs in the charts at the same time.
The DJ worked with the "Umbrella" hitmaker on dance track "Who's That Chick", which made the top ten in several European countries. But because the star's album "Loud" was released at the same time, Guetta's record label asked radio DJs to pull the track in favor of Rihanna's new work.
He tells Britain's Daily Star, "My record label sent letters to all the radio stations asking them to stop playing 'Who's That Chick' as Rihanna's album was out at the same time. It was strange because normally record labels ask radio stations to play your music."
