obnoxious signup screen blocking ITunes purchases

Hi

Just today I'm finding I can't buy anything from iTunes. Any search result I click on, this obnoxious "get music for free" screen appears, with all-too-easy "hey, we already know your credit card number, it's easy! We know you'll forget to cancel within a month" features. Click on "Not now"? Straight back to the search results.

Basically I can't buy anything without obeying this horrible marketing of Apple's latest scheme. I just want to find what I want, see the price, have a think and then pay for it. Is that so much of an ask?

Please, please, remove this foul thing.
