The closed thread on this subject was very worthwhile reading, so following advice I ended up on the PRS site and made an enquiry via an online enquiry form about how this licensing works. I got a standard answer that I needed two licences but no answer to a specific question. The contact has also not responded to requests to give me a contact who would answer specific questions.
I want to do the right thing and on the face of it these people are there to facilitate me doing the right thing and collect royalties on behalf of artists but it seems they are shy about answering specific questions and telling me how this actually works.
One question in particular has been ignored.
If I buy the license to use music for event videography how do I know the artists I intend using have subscribed to their royalties collection scheme ?
It makes sense to know this. What's the point of buying a blanket license to use a Bruce Springsteen track, among others, if BS hasn't subscribed to their scheme ?
I do have a few other simple questions but there is no 'contact' on this site to ask, just a default online web form and the responder at the other end of this query ignores specific questions and ignores requests to give me a contact who will answer questions ??
