Great DJ

Vocalist Katie White states that the song was written by "playing a D chord on the guitar for hours, because that's all I could play. And then I put my finger on the wrong string, and got what I discovered was an augmented chord. And that was the riff!"^[1] The single was originally released as a double A-side along with "That's Not My Name".

When "Great DJ" was re-released on 3 March 2008, it did not enter the UK Singles Chart until one week after the individual re-release of single "That's Not My Name" went to number one.

The cover sleeves for the single were recycled: Katie White and Jules De Martino gathered old 7-inch records from numerous car boot sales and charity shops in and around Manchester, turned the sleeves inside out and customised them to create new sleeves for this single.

"Great DJ" was featured on iTunes' free single of the week in Canada where it received an average of 3½ stars.^{[citation needed]}
