How to become a music journalist?

[Rick]

First you'd have to get a Journalism degree.
Then you'd have to toil in the field of journalism for a number of years to gain experience as a writer.
Then, if you're really lucky (and deemed to be very talented), would you have the opportunity to become a music journalist.

But you need to understand that journalism itself is a dying industry, and that there are even fewer jobs out there as a so-called "music journalist."
