In Bob Dylan's 2020 album Rough and Rowdy Ways, the song  "I Contain Multitudes" includes the lines:

I'm just like Anne Frank, like Indiana Jones
And them British bad boys, The Rolling Stones
I go right to the edge, I go right to the end
I go right where all things lost are made good again
I sing the songs of experience like William Blake
I have no apologies to make
Everything's flowing all at the same time
I live on a boulevard of crime
I drive fast cars, and I eat fast foods
I contain multitudes
