The logic and rationale of some of you
A-list celebrities who are primarily musicians
obviously don't fit the bill here, no matter how much you want them to
This thread is more for 'music as a 2nd career' type celebrities (Jared Leto, etc.) and flop acts who somehow manage to always keep their names out there (Rita Ora, etc.).
If we're going to name Beyoncé, Gaga, Madonna, etc. then the thread title needs to be changed to 'artists who brand themselves beyond their music.'
