As described in the previous step, it's fairly straightforward for software to update textual genre information in music files.
It's worth discussing, though, how bliss decides what genres should be assigned to your music files, and how you express how genres should be consolidated.
Let's start with how bliss is configured. Genre consolidation is all about reducing the number of genres in your music library. However, there's still a recognition that genre can be a useful mechanism by which your music library is organised because it can help to build playlists and decide what music you want to hear.
bliss stores an "allowed list" of genres that are permitted in your collection, configured by you. This list may contain a small number of very general genres, or it may contain many specific genres. It may contain a mixture of both, where your music library is dominated by certain genres and you need a bit more specifity to keep things organised in those genres.
Now, how is that "allowed list" applied? bliss assesses each album. If the album's genre is not in the list (it is non-compliant), it consults its own knowledge base of genres to see which of the list most closely matches as an appropriate substitute. It does this in a few different ways and attempts to choose a genre which is suggested to you before any change is made.
This is done for every album. Some albums fall into the "allowed list" and are compliant, others don't, are non-compliant and bliss attempts to suggest a fix.
That's the theory. Now for the practice! Let's look at how to configure bliss to consolidate music genres.
