The original instructions were for the original poster that wanted to have Explicit and Clean in MB but
also read the tags from iTunes.
If you don't want/need to read iTunes tags use ost's instructions.
If you want MB to read any iTunes tags that may already be on your files follow these instructions:
define a custom tag like this
then set the new custom tag to display here:
MB will automatically scan your library to see if any of your tracks have 'Content Rating' tags.
As the iTunes tag syntax is not in the form of 'Explicit' or 'Clean'
(it uses;
0 or null = No Rating,
1 = Explicit,
2 = Clean)
After the scan has completed, you need to set up a virtual tag 'Content Advisory' that you use wherever you want 'Clean' or 'Explicit' displayed
Content Advisory | $IsNull(<Content Rating>,,$If(<Content Rating>=0,,$If(<Content Rating>=1,"Explicit","Clean")))
Hope this clears up the confusion in this thread
