I am personally using and Qobuz and Tidal (because they complement each other in certain genres), but for my kids and wife we have a Spotify family subscription. They like all the crap songs on there, so I will probably have a hard time getting rid of Spotify.
The fact that The Fediverse apps are compatible with each other is amazing. This in theory means that one can create your own Fediverse app as long as its compliant to the specifications, right? For example, we could create a LinkedIn clone or something similar?
