To put it simply, music in MP3 format has been compressed, and the sound quality is certainly not as good as CD, but poor sound quality is just one of them.

The second is that the current protection of intellectual property rights in mainland China is not enough. The music we download for free is actually infringing, and is naturally called garbage by many people who value intellectual property rights.

Third, due to the popularity of free downloading of songs, many people no longer spend money to buy albums. As a result, the record industry is in recession, and record companies will reduce their expenses accordingly, including albums. The direct consequences of production fees and the cost of promoting new artists are that the quality of albums will decline and many talented musicians will not be promoted. At the same time, the decline in album quality will continue to reduce purchasing power, continue to lose customers, and fall into a vicious circle. There will be fewer and fewer good music and albums.

Fourthly, singers and producers sometimes have good intentions when arranging the order of album tracks. They want to express a feeling and idea. This is the difference between albums and singles. The album has an overall ideological structure, rather than a simple list of singles, and the songs we download to MP3 are exactly such a list, which affects the expression of the entire musical thoughts of the singer and the album.
