i'd think this place is full of shit. (excuse my language)
reason why? the Domain cxmusic.co.uk is using a Yahoo Small Business shopsites DNS server. This place is supposed to be pretty big, i doubt they'd be using some small ass service like Yahoo Small Business.
I hope you didin't enter your CC# or anything like that
