Five ways to organize your various artist compilations

Various artists compilations are compilation albums that feature tracks by more than one artist. To get the most out of compilations, making them more navigable in your music library, you need to treat them differently to other albums.

Unlike albums, various artist compilations do not make up one contiguous body of work by an artist. This means they often require some form of separation while navigating. For instance, say you are interesting in playing an entire album by one particular artist. You don't want to be shown individual tracks from compilations the artist may be featured on. Conversely, sometimes listening to a compilation is a good idea, and some compilations are works of art in their own right. You might want to search for and play a compilation, so you want the compilations organized together, rather than going through different artists, adding track by track.

Here are five considerations you should bare in mind when organising various artist compilations.

Use the compilation tag

The best place to start is to be explicit. If a collection of tracks is a compilation, it's only fair to tell your music player. This gives a 'hint' to your music player to make sure to group the tracks together.

The compilation tag is named as follows, and should be set for every track:

  Compilation tag
MP3 and MP4 (ID3v2.x) (.mp3, m4p, .m4a) TCMP
Ogg and FLAC (.ogg, .flac) COMPILATION

Specify '1' for the tag, when the track is in a compilation. If not, it's best not to have the tag at all.

The slight issue here is that neither of these tags are officially specified by the various specification bodies. Indeed, the MP3 tag 'TCMP' became de facto by its use in iTunes. So, the unfortunate thing is that your music player may not support compilation tags.

Avoid artist fragmentation

Each digital music file you have has two main fields in which you can record the artist. The first is the track artist field. The second is, de facto, called the album artist field. Here's how these abstract names map to the actual tag names required:

  Track artist Album artist
MP3 and MP4 (ID3v2.x) (.mp3, m4p, .m4a) TPE1 TPE2
Ogg and FLAC (.ogg, .flac) ARTIST ALBUMARTIST

Here's the problem: if only a track artist is specified, and that track artist differs for each track in a compilation (let's say because you wanted to record who sang/wrote each track) then without an album artist the compilation will be fragmented. Without an album artist, there is no overall grouping artist.

Undesirable compilation 'fragmentation' often occurs when ripping CDs for two reasons. The first is that CD rippers often look up data online, on one of the free CD databases. This data is not always reliable or consistent, and so only the track artist may be populated and this may vary per track. Secondly, the data may be available but the ripper itself may not insert album artist tags.

Various artist compilations

The minimum you should do is populate the track artist field. However, if you have populated the track artist field with differing artist names for each track, the album artist field should in turn be used to group the tracks under the 'Various' title. This gives you the most portability amongst different music players. Ideally, you should populate the track artist with the artist who performed the track, and the album artist with 'Various' or some variation (see below). This way, your compilations are still grouped under 'Various' yet when you perform a track search by artist, you should get both the tracks from the artists' albums and also those that appear on compilations.

Keep compilation, album name, year and album artist tags identical

To avoid fragmentation of a compilation, you need to make sure that every track has identical values for certain tags. These tags, the compilation tag, album name, year and album artist, are potential identifiers for the surrounding release and should be the same across any given release.

Album name and album artist are both obvious. If half of the tracks from the same compilation are tagged with the album "Greatest Hits" while the other half are tagged "Gratest Hits" they'll show as two albums. Correct the spelling, and ensure the tags are the same. This also extends to capitalisation of tags.

The year tag is used to specify the year of release of the surrounding album. Therefore, for compilations, it should be the year of release of the compilation, not the song. Keep this the same too, to avoid any possible variation in behaviour between music players.

'Identical' also means: if one of these tags is set for one track, it must be set for all tracks.

Decide on your 'Various' artist name

As well as keeping the artist name consistent within a compilation album, you should keep it consistent across your collection. It's annoying to want to browse all of your 'Various artist' compilations and realise you have to browse through 'Various', 'Various artists' and other variations to find all of your compilations.

I suggest choosing the name 'Various' (assuming you're English of course!). The lack of a space, and just having one word makes things more concise and easier to work with later.

Single art or album art?

On the subject of compilation fragmentation, art generally doesn't cause fragmentation because it's not seen as 'identifying' metadata by music players. This means you can choose art which represents each track by embedding it only in that track without fragmenting an album. For instance, for pop compilations or 'greatest hits' albums, typically all of the tracks will have been released as singles. You can find the art for the single and embed that.

If you do this, prepare for a lot of work finding and embedding the art. Few of the album art programs support this easily. I guess this would be fantastic to add to bliss at some point.

Furthermore, if you do this then you may need to remove any conflicting art file within the same directory as the compilation.

Finally, it's also worth checking your music player supports different art for different tracks in the same album. Some don't.

I hope these ideas have helped you improve your compilation album management!
