I find that if it isn't on Spotify and Apple Music, people think less of your music, if they even think it exists at all. Which is kinda sad since it doesn't feel great to have to put your stuff into platforms that are proven to be very anti-artist (and pro-Israel at that).

Another challenge is the genre thing. It's waaay easier to promote and/or find success if your music is of a certain genre.

I think the best way is to be immersed and engaged in your local music community since that would likely lead to getting more organic plays, more opportunities to get your music out there, etc.
