What is the definition of Angela Sounds?

Ah, 'Angela sounds' - the musical equivalent of a mischievous cat that purrs at random times, leaving a trail of confusion and bewildered melodies. Imagine this: "As Angela sang her angela sounds, the disco floor went into a full-blown musical tango, but instead of a dance partner, it was the very beat itself." It's like when you're trying to make out someone's mood, but the song is a cacophonous mix of love, anger, and existential dread all at once.
