You can also use a dedicated action combined with a filter.

Filtering for

`NOT genre HAS "Rock"`

would list all files which don't have "Rock" in the genre field. Then, applying an action **Format tag field** for field `GENRE` with `[%genre%,]Rock` would append the genre "Rock" to a possible existing genre.

You can use two actions **Replace** for field `GENRE` with

1. `, Rock` and
2. `Rock`

replaced by nothing (equivalent to removing) to remove the genre "Rock" from a possibly comma-delimited list of genres.
