Surround sound. Sound all around. Always something to hear, even with our hands over our ears. Even for those of us who are deaf.

Some sounds are more pleasant than others. Scientific research has been carried out into sound-waves and our experience of them. We “know” to an extent why certain sounds make us feel good, and others not.

As of today "Smells Like Teen Spirit" has accumulated 2,256,122,521 streams on Spotify. But it wouldn’t be many people’s definition of The Sweetest Tune.

There is much more to a good song, than a beautiful melody alone.
