E serves as a sign to remind parents and teenagers of some unhealthy messages and hints that may appear in these records.

The "dirty mark" (common name in mainland China) is a mark that, under the supervision of the ParentsMusicResourceCenter in the United States, requires some records to be placed in a prominent position on the cover to distinguish other records. This is somewhat similar to the American film rating system.

Dirty label is a mark that usually appears on the cover of an album to remind the parents of underage buyers to check the content because the content contains unhealthy elements (such as bad ideological guidance and lyrics with swear words). In addition to swear words, it also includes prohibited words, violence, anti-religion, musical parts and swear words. Therefore, you can be sure that the "labeled" record you buy is a version released in the United States. American records with such content should have labels. Extended information

After its establishment in 1985, PMRC formally submitted this initiative to the Recording Industry Association of America ("RIAA") in the hope that they could establish a review system similar to film classification in the music industry; in addition: Printing warning signs and relevant lyrics on record sleeves, forcing record stores to place records with explicit sleeves in inconspicuous locations, etc.

As a result, in November 1985, the RIAA agreed to affix a mark with "Parental Advisory: Explicit Lyrics" on the CD cover, which was the so-called "dirty mark". ?

In 1990, PMRC and RIAA joined forces to standardize the shape and color of the Parental Advisory logo, resulting in the black and white square dirty logo that we are now very familiar with.
