The Sound Boutique is a member of the Performing Rights Society (PRS). The PRS licenses and collects royalties when music is played and performed.
When do I pay a Perfomance Licence fee?
You pay a fee if you make a public performance by playing the music to the public. For example, let's say you make a corporate video for your client, who then shows that video at a trade fair. That's actually a public performance, and the client will be expected to pay a fee for the right to do this to the writer / composer via ASCAP (in the US) or PRS (in the UK). So it pays to think through to the final use of the music - if you write a midi file version of a hit song and put it on your website, no matter how insignificant that may seem so some people, technically you're due to pay your local Performance Rights Organisation for the right to do that.
If the performance is part of face-to-face teaching activity at a non-profit educational institution, permission is not required. Permission is required when music is used as part of training seminars, conventions, or other commercial or business presentations.
If you are in the US: ASCAP
If you are in the UK: PRS
