Please demonstrate how your statement is not the fallacy then. It should be clear to be a fallacy to anyone who likes music and never heard of the dude you're talking about, and there are just so many of us.

I'm not playing logic UNO with you. I can live with the fact that some person on the internet thinks I'm wrong.

No, you aren't playing "logic UNO" as you put it. You are just not having a discussion in good faith. As you first imply people never hearing about some musician are not "serious", and then you claim that having a logical discussion is somehow a lower form of a debate.
