I've personally never been a fan of Soundcloud. I think Bandcamp would suit your needs a lot more personally.
Bandcamp does have some active members and some kind of music discovery features, so you may find a few listeners there. It's just nothing comparable to iTunes or Spotify is all.
But! It's free and the fees are pretty minimal afaik. They have some nice graphs for stats and such too. Im a sucker for a good graph. 🤣
I think Soundcloud has uses such as releasing odd recordings that you might not put on Bandcamp. I found it years ago when looking for a place to easily post music. I even put some podcasts on there.
