Because music isn’t made to bring you down, it does the opposite. If someone notices me lying in bed staring blankly up at the ceiling, listening to ‘The Who’ it’s not because I’m sad and seeking divine intervention. Alright that last bit might be true but not the first.
See, most people get their entertainment from the TV or films where everything is played out for you. With a song, the lyrics and the sounds resonate a picture and a feeling that you create. You don’t intentionally create it, it just happens. It’s just like reading a book, only more fun.
The reason I probably lie in bed and listen to music is because I was sad, but ‘Tommy’ came and found me long before anyone came walking past my door asking questions. By that time I’m already lost in my head and in the music and at the point of happiness and calm as the sound waves massage my mind.
