Part of what makes us sluggish is that we get tired of the same stuff al of the time. Same food, same place, same job, same people — and music is no exception.
I listen to all SORTS of music over the course of any given day. New music. Old music. Video game stage music. Ending themes from anime episodes. Obscure disco music. Music from countries where I don’t even speak the language. All of it speaks to ME, though, for some reason or another.
But like anything else, if you listen to the same stuff too many times, it gets old. You start skipping songs after recognizing them within the first second of play. The magical feeling you may have once gotten from a song eventually resembles something more like a dull ache. You, along with your tastes, change over time — so why don’t we change the music we listen to in order to keep up?
