Heart-Shaped Box, About a Girl, Aneurysm, and some other ones go beyond that I guess. Even some other ones on Nevermind like Something in the Way are still hella popular, but it is a very well-known album by a very well-known band.
Heart-Shaped Box was one I definitely was thinking of for a non-Nevermind song, but if anything's going to be played on the radio it's those around five or six songs.
It's not like they had a chance to make that much material either, although some unreleased have been released on compilations, I think? In retrospect at least the rest of the band didn't continue as Nirvana without Kurt, they could've easily milked that recognition for years.
