A workaround is to export data to a CSV file, and then to generate reports using a tool like Excel.
There is a severe limitation to what can be achieved due to the paucity of data that is included in the CSV export file.
- no AlbumArtist tag, so the user is unable to properly produce a summary at the album level ... ie. without the albumartist tag, a single multi-artist composite album appears to be many albums, one for each artist
- no Composer tag ... so impossible to produce a Composer related report ... same thing with the Conductor tag
- no Custom tags
[UPDATE] see here for an illustration and more more discussion
