A Billboard chart headline made the rounds: "Olivia Rodrigo becomes the first woman in history to debut her first ten top 10 Hot 100 hits in the top 10."

Lynn quote-posted it a theorem that certainly made me giggle.

A hit song on the Billboard 100 charts is termed $k$-good if it is ever in a weekly top-$k$, and $k$-immediate if it debuts in the top-$k$. An artist is $(n,k)$-Olivian if their $n$ first $k$-good hits are all also $k$-immediate.

Headline 1. Olivia Rodrigo is the first $(10,10)$-Olivian woman.
