I'd argue Taylor Swift has done it too, and to a less mainstream degree Trent Reznor who has kept his career rolling along forever.

A core audience who will buy what ever you sell is key, and also not being afraid to change your style from album to album

I think Taylor Swift is on track, but I'm not sure she's old enough yet. She's arguably in her early 30s, while Beyonce is 42. I'm sure Taylor Swift will still have multiple hit records in her 40s, but currently I think it's rare.

You might be right from with Trent Reznor - Pretty Hate Machine dropped when he was was 24 and With Teeth went Gold when he was 40. This is roughly the same as Beyonce current longevity (Cowboy Carter, Beyonces latest album, which she released at age 42, has also only gone Gold)

You forgot the intergenerational ur-artist: "Weird Al" Yankovic.
