Not sure what to recommend outside the obvious... but as far as streaming goes, Picarto's really popular, I heard Piczel's a runner-up. If you also need a start on what program to use for that, try Open Broadcaster Software! People often put on music or stream a show in the corner while they do their thing, and sometimes they talk, though I don't usually listen to the talking myself.

I think people usually end up with small/inconsistent viewer counts, but it can still be a thing and worthwhile even then, I think?
