You can search for Shangzhiyin or SG Shangzhiyin on Baidu. Two official websites will appear. Click on the SGMOOD link to enter his copyrighted music website, which contains various types of music. Music can be chosen. It is very convenient to play, purchase and operate in it. It is also classified into various categories according to different usage scenarios and store types, so you don’t have to worry about too many choices and don’t know what to choose. Moreover, the music taste inside is quite good, and there are various different music styles, which can be selected according to consumers' preferences, and the price is also very close to the people. My cafe now uses the music I found here, and customers like it quite a lot. I feel like more people are coming.
