In the near-end of 2016, an abandoned cassette came to life through unkown ways, reportedly from the contemporary scientists. They also say that this cassette can actually generate ambiental sounds, that shape the actual definition of a dream.
あなたの愛と調和 / HARMONY_WITH_YOUR_LOVE - this is how they called it, based on the way that the cassette played with its own sounds.
However, the cassette has been considered something really unique, as the both tracks the scientists recored have a 30-minute length - with a 1 second error for the first one.
The scientists hope to find out more about this mysterious audio box, as it seems promising for the actual music industry in some ways.
