There's a reason some young people are rediscovering these numbers.
They all understand that the quality of the music, the fidelity we had back in the days it is not the same as playing mp3s.
These numbers were the Record player speeds. When we only had vinyls, and no matter what they say the quality is audio was a hundred times better than what it is nowadays. Most of the records were at 45, very few at 33, and even fewer at 78 or 16..... Please SHARE if you had a record player and remembered these numbers
