If ya like making music on an iphone, you need this. It kicks butt. Never been free before, AFAIK. Might not be free yet, if not, wait a couple hours. App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
It's been free 4 different times according to appshopper. I already have it, and I'm relatively certain I got it for free last year on Black Friday.
You are probably right, but this isn't a "every other month for a week" freebie. This is a once a year for a day freebie. EDIT: And it was on my wishlist forever.
