Hey that is good thinking Two Tired...
When my kid is being a little snot instead of punishment I will give a high five... see how that works out, lol.
Depending on the kid's age, either action may give him exactly what he wants; attention, and not change his long term negative behavior pattern. Older kids can better differentiate between negative and positive attention. Younger ones just do what gets them the most attention, especially if they have to compete with others for that attention. Children are very good at learning how to push the parent's buttons, in order to manipulate their environment.
If your kid develops a pattern of being a snot, you are probably reinforcing that behavior in some way, if unwittingly.
If they are trying out different music/art in order to elicit strong emotions and unsettle you, don't let them know it is working. You'll just get more of the same toward even more extremes. Unfortunately, not all parents know this. Even if you do, the kids can pair up with other kids, who HAVE learned just how to get under their parents skin, and then try out approaches on your that worked for them.
It's never easy...
Cheers,
