As a musician/producer and former music teacher I think this is a brilliant idea. It is a great way for young artists to find an audience and a potential market for their artistry away from the noise of established platforms and online stores. Also a great alternative to SoundClound given their uncertain future (even with the possible investment in the works for them).
What is the best way to get onto the platform or to introduce it to other artists looking for new distribution channels or exposure?
