The animated character videos appearing on the low-quality tech Lo-fi music are popular around the world. Short for low fidelity, Lo-fi is non-lyrics. They are combined purposefully, giving a feeling of lightness, soaring. That is why people also call Lo-fi music for dreamers.

On YouTube channels like ChillHop or DreamyCow, Lo-fi videos attract millions of views. While livestreams last for many years, there are always tens of thousands of followers.

Livestream with the image of a girl doing homework on Lo-fi music was the longest live video in YouTube history. This channel created a new live stream and is still playing after 10 months.

Lo-fi listeners will find it easy to realize that they often contain the sounds of hip hop, soul and jazz. In the 1960s and 2010s, the top 100 US Billboard songs that influenced the pop music genre were mostly hip hop.

Most Lo-fi music also contains the sound of boom bap – the hip hop style that dates back to the 1980s and is still popular today. That is the reason why Lo-fi brings a feeling of familiarity with many generations even when listening for the first time.

According to Blackman, the hip hop style used in Lo-fi music is a material that helps listeners focus on studying and working. Lo-fi music is also popular with therapists. Michael Viega, a music therapist at the University of Montclair, often uses Lo-fi music to relieve stress.

The repetitive melody of Lo-fi music also helps the listener relax. Victor Szabo, the music professor is writing a book on Lo-fi, explaining that repetition makes Lo-fi more predictable.

Independent studies have proven Lo-fi music increases learning and working efficiency. One survey found that 86 percent of participants said their productivity was better thanks to listening to Lo-fi music.
