I heard about AUDIUS view months ago, its not even from crypto community just a local hip-hop scene promoting their music. Their usecase is not unique and its kinda mainstream just like Soundcloud but better, but they have great grassroot marketing and promotion thats why they can be successful, some people that are using AUDIUS does not even realize they are using crypto project for a while.
For Moozicore I don't necessarily think they have bad fundamental, they just don't bring anything new compared to to other platform.
If you look into other earlier crypto project that related to Music, you can check Viberate, they were very big and attract so many people back then, They offer totallly new Idea about discoering new music, but it slowed down a little bit now.
It still have many user base tho,
the only reason why audius is successful is binance. for no other reason, their promotion strategy is the same as any other project, even moozicore does the same thing as audius. but look at the binance effect has the most part. and despite all that, their platform still doesn't have a large number of users. So I don't think it's good yet.
