FAQ: How can I ensure multi disc sets and box sets are identified properly?

If you’re importing a multi-disc set, the best way to ensure it’s identified properly is to make sure the track listing matches the original release.

Identifying Multi-Disc Sets

For best results, make sure the whole set is in its own folder, and make sure the file tags include:
  1. The name of the album (meaning all discs have the same album title)
  2. Accurate track numbers, (meaning each disc starts with Track 1)
  3. Accurate media numbers (meaning each disc is numbered Disc X of Y, with Y being the total number of discs in the set)

Directories

We look for a couple of different possible folder structures when it comes to the individual discs. So this scheme will work:
Music/
    Miles Davis - The Complete Columbia Album Collection/
        01-01 Track.flac
        01-02 Track.flac
        ...        
        02-01 Track.flac
        02-02 Track.flac
        ...        
    Pink Floyd: Discovery/
        01-01 Track.flac
        01-02 Track.flac
        ...        
        02-01 Track.flac
        02-02 Track.flac
        ... 
And this will work just as well:
Music/
    Miles Davis - The Complete Columbia Album Collection/
        CD1/
            01 Track.flac
            02 Track.flac
            ...        
        CD2/
            01 Track.flac
            02 Track.flac
            ...        
        ...
    Pink Floyd: Discovery/
        CD1/
            01 Track.flac
            02 Track.flac
            ...        
        CD2/
            01 Track.flac
            02 Track.flac
            ...        
        ...  
One thing that likely won't work is having all the discs of a box set separated into album-level directories, like this:
Music/
    Miles Davis - The Complete Columbia Album Collection CD1/
        01-01 Track.flac
        01-02 Track.flac
        ...        
    Miles Davis - The Complete Columbia Album Collection CD2/   
        02-01 Track.flac
        02-02 Track.flac
        ...        
    ...
    Pink Floyd: Discovery CD1/
        01-01 Track.flac
        01-02 Track.flac
        ...        
    Pink Floyd: Discovery CD2/
        02-01 Track.flac
        02-02 Track.flac
        ...        
    ...
Don't do that!

Fixing Errors

If a set you've imported doesn't seem to be identifying properly, you can edit your files directly, or you can edit the album in Roon. If your set is split up, you can select the various discs in the album browser, and then choose Merge to combine them into a single disc.

You can also select the disc (or click Edit under the 3 dots menu while viewing its Album Details screen) and choose Identify, to search Roon's database and try to find a better match.
