According to our information, live music was performed at the events in question. You had already received a licence or licences from us on the basis of the tariffs for live music. Since you had not objected, you received the invoice in question from us.
You may, however, request a change via our Online Portal under My invoices. Please enter wrong tariff features as the reason for the change.
For your information: If you do not get active, you must submit a setlist for live music, which is not possible if you have used sound recordings or streaming services.
