Some off the Queen songs are quite catchy and instantly appeal to a large public. They're more of an iconic band. The name of the band is also quite good for their identity.

Californication is a radio tune. There's more to RHCP than that. I won't pretend it's sophisticated like John Coltrane, Nils Petter Molvær or some cult band like The Doors or The Velvet Underground, but it's still something to dive into and listen to carefully if you have the time and inclination. It's also less niche than INXS for instance.

People (outside of Korea too) listen to Black Pink and BTS. Which is totally fine, but the last ones are more proficient on the dance and show side of things. Also, having mentioned Korean girl and boy bands, I find Psy's Gangnam Style song quite satyrical and also very catchy.

guess this is anecdotal based on my experience but RHCP seems to be very popular worldwide. Especially considering in many countries popular American music is played many years after they are a hit in the US. RHCP plays overseas nearly every tour and seem to be absolutely massive in South America (just go to any RHCP youtube video, and look at all the comments like "please come back to Brasil!"
