I'd say streaming radio in general is low profile in how it lets you discover new things. I use the search/directory built into foobar2000 or apps like radiodroid, but there are sites like https://www.radio-browser.info/ for the web. It's an interesting and low cost way to find things you wouldn't otherwise be exposed to and likely curated by whoever is running the station. What really stood out to me is how different countries or regions have their own tastes, or at least are likely to be playing something different to local broadcasts.

Also adding Radio Paradise, apparently one of the first online radios (https://radioparadise.com/). That said, it does have a skip (and pause) mechanism, so if you really don't like something you can skip to the next one.
