Good is in the eye of the beholder. Its irrelevant. The question is can he make a living off the music he's making. And the answer is absolutely no way.
Working in the music industry has taught me a lot of things, and if there's one absolutely genre-superseding fact that I have learned is that talent has almost absolutely nothing to do with "making a living" in the music industry.
Common example thrown around Nashville a lot: Taylor Swift would not be a "star" had her dad not pumped approximately $3million into her career at the outset. Trust me, I have come across more musicians with more talent in their pinky finger than Taylor Swift has in her entire body.
I wish I could listen to the tracks to pass judgment, but the site is currently unavailable. I'll have to check the tracks out another time. But all of this is moot, seeing as how anymore, 99% of musicians AREN'T going to be featured on TV, or radio, or ANYTHING of that nature unless they have money to back their career and a damn good manager.
