SECRET CONTENT - SECRET NUMBER invites fans to listen to relaxing music through a playlist entitled "Secret Lo-Fi Radio".
The music is broadcast on the official YouTube SECRET NUMBER channel
Lo-Fi music is known as music to relax because it is only an instrument without vocals and there are real sounds such as birdsong, the roar of cloudy clouds, stirring spoons against glasses, and even the sound of flipping books.
Lo-Fi comes from the word low fidelity, which means the music is produced in low quality. Many people admit that these low notes and soft melodies can make them focus more while working and studying.
So, it is common to find this type of music on YouTube with a vector graphic display of a person studying in his room.
This music has existed before 1990 and returned to popularity in 2017 on the YouTube and Soundcloud platforms. In fact, many contemporary songs have been converted into Lo-Fi types, such as K-pop songs.
