Why Do People Prefer ‘Certain’ Kinds of Music and How Does It Affect Mood?

Imagine you're in a classroom, and someone starts playing your favorite song. All of a sudden, you feel happy or even energized, that's because your brain likes the kind of music you choose! Some people love fast songs like rock or pop, while others prefer slow tunes like jazz or classical music. Music can change how we feel: it might make us sad, calm, excited, or even sleepy. It’s like a special kind of magic that affects our mood just by playing sound.
