How do singers, especially lyrically dense rappers, memorize dozens or even triple digit number of songs?

Question

I’m notoriously bad at memorizing lyrics so it’s mind boggling to me.

Answer 1

I’ve never written music or a song but I know the words to far more songs than most artists catalogues, even down to the small details of a cadence/flow, different tone that may be used, or duration of pauses and adlibs etc…which is weird as in general I have a really bad memory!

Think of it as muscle memory, when the song starts I remember the first line and each line just automatically flows into the next through that muscle memory.
