I would like to write the `COMPILATION` tag in mp3tag.

The trouble is if I save the file and open the properties in foobar2000 the tag appears as `ITUNESCOMPILATION`.

I'm not sure what mapping I need in order for this to work in mp3tag.

I don't think that you need any mapping at all. foobar2000 decides to display the compilation field as `ITUNESCOMPILATION`, but if you write from Mp3tag `COMPILATION` is the way to go (it writes to `TCMP` for ID3v2 and `cpil` for MP4).

The trouble is I'm writing to FLAC and MP3.

If I write to the `COMPILATION` tag for FLAC, it's fine but then in foobar2000 it's different to the `ITUNESCOMPILATION` for the MP3s.

I suppose all I can do is map `VorbisComment` like so?
