Music licensing body ASCAP has introduced an interactive license rate calculator called the RateCalc, designed to help Internet music users compute their ASCAP music license fees. The RateCalc allows users to find the best licensing option by answering four questions, ASCAP said. It also shows a comparison of the costs of all three options. Users can choose a license option from the RateCalc and start the agreement process. ASCAP introduced a new licensing structure in December.
