As apparently, this move is made to target audiobook listeners and podcast listeners, can I recommend https://audiobookshelf.org
The revenue from streaming services always pales in comparison to buying the music directly from an artist. The streaming model has been hijacked by record labels who take the majority share, such are the deals they force artists to sign.
A decent number of artists offer digital downloads of their music directly either for a flat fee or in a pay what you wish system.
It is nowhere near as convenient unfortunately. Benn Jordan mentions some options in several of their videos about their experience with Spotify, but i’m admittedly not certain I just linked the right one.
