The Saturdays have released a remix app thingy called, somewhat prosaically, The Saturdays Remixer.
Ever wanted a program allowing you to remix 'All Fired Up' on the Apple touchscreen device of your choice and post it for the viewing pleasure of your friends on Facebook? Great! For £1.99 you can do that and not much more.
The Saturdays Remixer can be bought from the iTunes App Store and comes with two other songs for you to make less good versions of, namely 'Ego' and 'Higher'.
