Vinyl record is the dominant music format in the 20th century. From your 78 year old grandmother to your 45 year old celibate, because the sound quality of black glue is closest to the original sound without distortion, it feels more fidelity and perfectly covers people of all ages. Black glue, also known as LP, long play, is a stereo black Celluloid texture compact disc.
Since 1948, 33 and 1 / 3 of the records have been released. After several years of development, the single-sided recording time is nearly 22 minutes, which is much longer than before, so it is called long playing. In contrast, with the original state of science and technology, there was the so-called “SP”, that is, standard playing, which was 78 revolutions per minute. Now the popular records are almost all 33 turns, so the vinyl records are directly called “LP”.
