Several movie and TV sites have come and go where you can just visit and watch without even creating an account. Quality might not be as good as a paid service and they are no doubt in the grey-to-red zone legally. I don’t see the same service for music.
Why do you think is there such a difference in trends?
but there are… many only know Spotify but we got SoundCloud aswell, deezer is free and has many more Songs. i sonst usw any oft that but many people forget Theres not just spotify
