i like traditional musics from around the world so when i fancy something new i start with wikipedia articles on instruments i like and rabbit hole through links to get terms and countries and things to put into search strings on youtube. One day i started with tar (precursor for both sitar and guitar) and ended up grooving to Philippine boat lutes, which are brilliant. https://piped.simpleprivacy.fr/watch?v=K7hYfnG7mJM

Trad musicians tend to play in several groups so that's another source of rabbit holes to explore. And just keeping an eye out for interesting things other people post. Mostly individual clips but sometimes happen into treasure troves like at the start of the first lockdown when someone I followed on Twitter posted about Met Opera in NYC streaming a different opera each day for free. It was a great opportunity to learn about a new-to-me type of music so I grabbed it, thinking it would be a couple of weeks at most. A year and a half later they finally stopped and I was an addict :)

Also libraries. Libraries can be fantastic for exploring new musicians and types of music.

Even when algorithms are good, there's still a lot more out there waiting for listeners ❤️
