VERSION tag ignored in VorbisComment

[ghost]

Expected behavior

For tracks with a subtitle either SUBTITLE (ID3) or VERSION (VorbisComment) is used.

Actual behavior

For ID3 (.mp3) it works with the SUBTITLE tag, but for VorbisComment (.flac, .ogg) the VERSION tag is ignored.

Steps to reproduce the behavior

1. Tag an audio file (.flac or .ogg) with a VERSION tag, for example “12 Inch Version”.
2. Scan for new audio files.
3. Share the file and look at the sharing page.
4. There is no "Subtitle" info displayed in the Share Player.

Possible solution (optional)

Detect the VERSION tag correctly in fLaC and OggS.
