Singular isn’t about scale
Tracy Chapman was outsold by the Doobie Brothers by 40:1. But the Doobie's aren't 40 times as singular an artist as she is.
Lou Reed was outsold by Van Morrison at least 40:1. But again, our image and memory of Lou compares to Van's, it's not a tiny fraction of his.
Singular is the one that we can tell apart, the one we remember, the one we will miss when it's gone.
It's entirely possible that creators with scale are also singular (like Van, or Miranda), but it's not required. Many of the artists, leaders and teachers that have had an impact on you and on me have done so with very little popular acclaim.
It doesn't pay to trade your singular-ness for scale.
Singular might lead to scale, but popular is not enough.
