>>19464363>maybe have a karaoke stream for funKaraoke streams aren't just for 'fun' (though of course they are fun, I personally find them more interesting than videogames), if you're a good singer like Suisei they can basically turn into the backbone of your content.
Also you dismiss music production as being only 'for novelty', but novelty is basically at the heart of every merch release. A fan of Pekora is going to buy a physical Pekora music CD just like he would buy a Nendo or a wall scroll - because it's a new product and hardcore fans enjoy being completionist.
