Yes I too was suckered in. Paid for Frostwire for my daughter's PC then found they were scamming $5 a month from me.
Their 'helpline' too is a scam - huge call charges followed by a greasy toe rag who kept asking me to repeat every letter, one by one, of my name and e-mail addres, put me on hold, repeated the questions blah blah then wanted all my credit card details...
I've reported it to my bank.

Spread the word mp3musichq is a very glossy scam!
