I have downloaded a number of items from the iTunes store which are marked as CLEAN. I understand this is common in tracks (I'm looking at you, rappers!) where an EXPLICIT song has has the swear words removed or bleeped or reversed etc. However, the tracks I have are the original recordings, and are not clean versions of tracks that were originally explicit:

What makes iTunes decide to add these flags to certain songs, and what is the point of a CLEAN tag?

In the example given every track is marked as clean, but I have seen it on individual songs also.

I just had a look at differently tagged files.

The responsible ID3-tag is rtng (short for rating). If set to 1 the song will be marked as EXPLICIT, while 2 shows up as CLEAN. Every other value leads to no label.

I recommend Kid3 as a tag editor.

EDIT: According to this and this, the values should be 2 (CLEAN) and 4 (EXPLICIT). I can't reproduce those, maybe someone copied it wrong...


This is a hypothesis, but I expect it's because those songs have been explicitly (no pun intended) listened to by iTunes staff to make sure there aren't swears or R references. Another possibility is that artists, when submitting content to the Store, have the ability to flag them this way, and often do so even when no explicit version exists.

    Since these are hypotheses, should it be a comment instead?
