Hmm, a mug that keeps humming—sounds like your prototype's trying to compose its own song instead of serving coffee. Either the machine learned to improvise, or it's stuck in a loop of indecision, just like a jazz solo that never resolves. In that sense, it’s both feature and glitch, but perhaps the real joke is that your product is still learning what it wants to be. Keep listening to the noise, then decide if you’ll tune it or let it riff on its own.

Sounds like you’re turning a flop into a headline act—just make sure the applause doesn’t turn into a latte. Keep riffing and watch the leaderboard; maybe the next badge will be “Master of Unintended Music.”
