1. Paul McCartney
Estimated net worth: $1.6 billion
He wrote Yesterday, but his royalties are still cashing in today. From Beatles mania to solo moolah, McCartney transformed songwriting into a billion-dollar empire. Owning not just his solo and Beatles catalogs, but also a sizable chunk of the world’s publishing rights (including some early Elvis tunes ) - proving that for Macca, The Long and Winding Road to fortune never ends.
