Song 4 Mutya (Out of Control)

"Song 4 Mutya (Out of Control)" was written by Andy Cato, Tim Hutton, Karen Poole and Tom Findlay, and produced by the former two under their stage name Groove Armada.^[2] The song features uncredited vocals by English singer Mutya Buena, a former member of girl group Sugababes.^[3] The song was included on Groove Armada's album Soundboy Rock (2007), and Buena's debut release Real Girl.^[2] It was initially intended to feature British singer Estelle with the title "Song 4 Estelle", but according to Groove Armada, "she didn't nail it at all".^[4] The production duo revealed how Buena ended up on the song, saying:

We needed an iconic voice. It's the voice of a generation, that generation of female pop acts. The same way that Robbie Williams left Take That at the right time, she left Sugababes at the right time. The Sugababes are a bit random for me now. It doesn't work any more. She's one of those pop voices, when you mention her, people don't go "What are you working with her for?" They go "She's cool." Mainly 'cos she's so scary.^[4]

They also spoke about their hesitance regarding the collaboration with Buena:

I thought she would be a little monster. Mutya came into the studio and she was nice. You forget how young she is - she's 21 - so she has her little mobile phone and is on it to her little mates talking about getting the right colour of hair dye. And in the middle of this you're trying to write a track. She has her own opinion and she can really sing - she's a very good performer.^[5]
