Yes - for me it was also a lot of manual work. I did it the following way:
- I Used Composer field for composer
- I used the B&W way for Album: Verdi, Giuseppe - La forza del destino (1954 - Serafin) - Callas Remastered (it was a lot of manual work to get that done for all the stuff I have)
other example: Wagner, Richard - Götterdämmerung (1964 - Solti) - BD (BD = Blu Ray disk edition)
- I introduced the work field e.g. La forza del destino
- I used compilation field with following values: Artist, composer, conductor, genre, Orchestra, publisher, Record Lable, Theme
- Grouping field with values: Mixed, Modern, Classical
- for classical music Genre is always classical , i used subgenre for diversification
- Artists : all artist part of the album
- Conductor in the conductor field
There are many ways to tag classical music but there is no standard. My decision was along the most popular shops like HighResaudio, Linn etc. how they tag classical music.
