On "Let You" Cheryl Cole sings about mistakes made in past relationships.
Cole told Stella Magazine: "I've been with men who were controlling, who made me unhappy, but I allowed it to happen. Women let these relationships happen, and that's what this song is about. But once you see it and recognize it, you have to try and not let it happen again."
She continued: "I own my mistakes. I've learnt more from them than I have from my successes. I've learnt how hard it is to be happy, and now I can honestly say I am happy."
"Let You" was co-written with Cole's Girls Aloud bandmate Nicola Roberts. The other writers are Chiara Hunter, Danny Casio, George Astasio, Jason Pebworth and Jon Shave. Production is by Mike Spencer.
Cole told the BBC that though the lyrics are personal, she's not just speaking for herself. "There was a girl in the room when we wrote it who was up to here with men problems, so I was wringing her for ideas! So it's not autobiographical, although there's definitely things I've experienced in there. I want it to be everyone's song. It's universal."
