Some people don't think that humor belongs in music, and that's okay. But it's kind of like calling Weird Al cringe. It makes me think that you don't understand the artist.
Weird Al doesn't sing about undead teddy bears, vampires, and the beast of pirates bay. Weird Al sings about being fat, discount groceries, and being stuck in the drive through.
Tastes are subjective and you're in here questioning the validity of my taste. Perhaps it is you who needs to take a step back, assess your stance, and fuck off.
