It's a fire? No, it's a stone What is it?

I can be a children's toy or an instrument in the professional league, Either way, both can cause auditory fatigue.

A continuous flow of water or mud, but also of series, movies and whatnot.

I am a tiny slice, so thin and slight, a narrow shard that catches light. Not whole, not much, just barely there, a little piece of something rare.
