Premium Service Our Premium Service provides Premium Subscribers with unlimited online and offline high­quality streaming access to our catalog. In addition to accessing our catalog on computers, tablets, and mobile devices, users can connect through speakers, receivers, televisions, cars, game consoles, and smart watches. The Premium Service offers a commercial­free music experience. We generate revenue for our Premium segment through the sale of Premium Services. Premium Services are sold directly to end users and through partners who are generally telecommunications companies that bundle the subscription with their own services or collect payment for the stand­alone subscriptions from end customers. We offer a variety of subscription pricing plans for our Premium Service, including our standard plan, Family Plan, and Student Plan, to appeal to Users with different lifestyles and across various demographics and age groups. Our pricing varies by plan and is adapted to each local market to align with consumer purchasing power, general cost levels, and willingness to pay for a music service. In addition, as we have entered into new markets where recurring subscription services are less common, we have expanded our subscription products to include prepaid options and durations other than monthly (both longer and shorter durations), as well as expanded both online and offline payment options. 101
