If you're like me, you probably can't get that fantastic soundtrack from Jetpack Joyride (5/5) out of your head after a quick run through and nothing short of hearing it again will help to scratch that itch. Thankfully you can now get your fill of the fine work by Cedar Jones as Halfbrick have uploaded the soundtrack (along with some juicy bonus tracks) to their Bandcamp page.
While you're there you can also check out the music from their earlier titles (for me it was like a treasure-trove of delights!), from Echoes to Raskulls.
The only problem I have now is making sure I don't listen to the soundtrack while driving 'cause I might just get a bit distracted ;)
