How can آپ tell if یا when an عملی حکمت series یا عملی حکمت movie is being play on the screen just سے طرف کی LISTENING to it from a distance (and when you're someplace else within hearing distance)?

The opening song یا credits help me. Certain عملی حکمت series یا فلمیں have particular openings that are unique to them. For example, I know when Yugioh is on when the voice of Yami (Dan Green) says, "Previously..." یا the opening theme starts playing.

This is the full theme song, but those opening notes are distinctive to Yugioh.
