Confuse on "Clean" tag on the songs

If it has the "Clean" tag it means the cussing in the song has been edited (like instead of a cuss word it will use a more kid-friendly alternative phrase) or censored.

Note that what consitutes "clean" or "explicit" is up to the record company, and that determination varies from company to company. Some companies seem to tolerate more in terms of language without marking a track as "explicit" than others, or may mark a track as "clean" where some other record company would not bother.

Regards.

What I understand about the "Clean" tag is that it is safe to listen to even for kids; no offensive or cussing in the lyrics. Am I correct on the use of that tag?

Absolutely not.

"Clean" means it is an "Explicit" song that has been cleaned up to somebody's satisfaction, but the message is still quite recognizable even if the non-clean words have been removed. The usual versions of hip-hop songs that you hear on the radio are done this way.

Songs that are actually clean are not labeled one way or another.
