What do you mean by 'explicit lyrics'?
When uploading your release, you must indicate whether it contains “explicit lyrics”. These are texts that are sexually explicit, contain abusive words or curses or are otherwise unsuitable for minors. In some countries - in particular the United States - it is mandatory to indicate this in advance, so that a warning can be placed with the relevant release in the download stores. You can compare it with the Kijkwijzer for films.
