IT'S YOUR DYNAMITE...
...is a very, very good track. The intro reminds me of Out Of Control 'bonus' track We Wanna Party and the instrumental bit sounds very much like the Xenomania remix of Sexy! No No No..., but that's actually not bad at all. The vocals are okay most of the time (Cheryl and Nadine sound the very best of all, Sarah sounds a bit meh), the lyrics are actually quite good, and the instrumental bit is insane (read: pretty damn good).
I don't dare compare It's Your Dynamite to Memory Of You or even She, but Dynamite is another Girls Aloud B-side that deserves to be much, much more. The Out Of Control album is good, but it would've been brilliant with these B-sides added (and Revolution In The Head killed).
Also: Out Of Control tour vids. I've seen them. OH MY GOD I so wish I'd live in the UK right now and wouldn't have to blame my final examinations for not being able to go (and the lack of money).
