Final answer:
Spotify is a subscription on-demand service, allowing users with a paid subscription to select specific music or podcasts to stream.
Step-by-step explanation:
Spotify is an example of a subscription on-demand streamer. This means that users pay a recurring fee to access Spotify's extensive library of music and podcasts. Unlike noninteractive services, Spotify allows users to choose exactly what they want to listen to. Streaming music from satellite transmission programs, while nonexcludable and available to anyone with a satellite receiver, differs from Spotify, where content is locked behind a subscription paywall and is not freely accessible by everyone.
