Yeah there is, if you’re good, know how to hustle a little bit, can build relationships and you take advantage of social media/the internet. I know a ton of musicians who do well with music. A few have made millions.
He's chosen an unconventional career that is dependant of whether the general public likes you or not..we always complain about how the truly great willm never get shine in this era of music, so its a bad choice he has made.
