I can't speak about Deezer specifically since I'm not familiar with their product, only their name. There's a little FAQ up at
https://ampwall.com/faq-alpha that might answer many of your questions, I'd prefer not to go full Pitch Mode on HN. But in short: artist-owned and operated -- I am the first user and have skin in the game that goes beyond money, incorporated as a Public Benefit Company, with a distinct vision that is more inclusive of music culture beyonds just bands and labels. It'll take time for the vision to be realized but we're on the right track. Happy to answer any other questions through email if you'd like, hails@ampwall.com or chris@ampwall.com.
