well.. The 4.0. Is just for a pathetic fun of a party.. The most i regret of Sugababes is Mutya and Siobhan Departure, we can't say Heidi is a lucky charm who brought Freak Like Me #1, it was because Mutya and Keisha! I love how Mutya vocal is.. I just regret she received a shorter verse that Heidi in Push the Button, Mutya always been pretty to me than other babes.. Keisha just trying to be "Beyonce" in Sugababes, like she kicked out Siobhan like Beyonce kicked out Letoya and Latavia in Sugababes, and try to sing over the song especially in Change and Catfights and Spotlight, yeah.. Like Beyonce.. She dare to do it cause No More Mutya that more vocal friendly than her.. That the truth is i feel comfort to listen Mutya than Keisha..
