> I'm honestly pretty sick of all the 60s-80s stuff I've been listening to, but what else is there?

Listen to a whole album. This is THE fundamental problem with streaming.

Any band that produced one good song probably produced quite a few other good ones. Bands that got pigeonholed into a "sound" probably produced other songs on their albums that weren't in that sound.

Even for mega-popular bands like "Journey", for example, 3/4 of the songs on their albums never get played anywhere. You'll probably find something you really like in that set.

Sadly, this seems to break down starting in the late 1990s.
