If you're not a fan of Bruce Dickinson and Iron this probably isn't a deal for you otherwise read on.
The soundtrack for this CD retails for around £9 alone so getting it free with the film for £10.99 isn't bad in itself. However if you use the code 'Chemical' from this weeks Kerrang you get it for £9.99
Please note play.com say soundtrack is only free for pre orders while stocks last.
I should add I've no idea if the film is any good, from all accounts it sounded pretty awful but entertainingly awful which suits me :-)
