Query: This '7' is a perfect 10!

The album 7 is the best album of S Club 7. All of the songs on it are great! It includes songs in which you get to hear every member of the group take a major part in. Usually Jo or Bradley act as the lead singer but there's songs on here in which Tina and Paul take the lead role. This is a GREAT CD, and every true music fan will have it.
