1. Wim Mertens is split into two entries.
There are two different artists in the database, but this is the same person and needs to be
One has 4 main albums (Double Entendre, Nosotros, Shot and Echo - A Sense of Place, What You See Is What You Hear), the other the rest (thirty something).
2. Balanescu Ensemble
I think that Balanescu Ensemble can be joined with Balanescu Quartet. It is only an entry that occurs as Jonathan Goldstein “Cyclorama” album (where also Balanescu Quartet is listed), does not have any other albums or metadata available.
Also Balanescu Quartet and Ada Milea - this is another single-album entry and the record itself has listed Balanescu Quartet and Ada Milea as separate contributors.
3. Dälek Vs. Faust
This is another single album entry for an album where Artists are Dälek and Faust.
(and the description is for Dalek obviously).
4. DJ Spooky that Subliminal Kid
1 album entry for DJ Spooky (that Subliminal Kid).
5. Giovanni Domenico and Giovanni di Domenico
The same main album, the same person.
6. Dresch Dudas Mihaly Quartet and Dresch Dudas Mihaly Quartett (written without the diacritical signs)
Two different entities, albums split between, one with wrong spelling (quartett).
7. English Opera Group Choir and English Opera Group Orchestra
Two entities, the same album (which has English Opera Group on its cover).
8. Henryk Gorecki
This is a the same person as Henryk Mikołaj Górecki (and usually the latter name is used in most cases), a well known Polish composer.
I know that the albums under Henryk Gorecki list him as such, but this is the issue of English language people writing Polish names. Believe me (but verify, of course) that this is the same person.
Also HMG entry has less albums but more metadata (nationality, born, died, Wiki), HG has more albums but no metadata. And Henryk Gorecki is wrongly sorted under H.
9. Hesperion XXI, Le Concert des Nations, La Capella Reial … (without diacritical signs)
This is an single entry made from multiple artists, and it should occur under Hesperion XXI.
10. Jordi Savall, Montserrat Figueras, Hesperion XXI, La Capella …
A single entry of many artists, and sorted under J.
11. Jordi Savall | Dominique Fernandez | …
Ditto.
12. Kronos Quartet, London Sinfonietta Orchestra
Ditto.
A single album, should be under Kronos Quartet).
13. La Capella Reial de Catalunya
Two entries of the same name. One has all the goods, the other just a sigle album and no data.
14. London Symphony Orchestra
Two entries, one spurious with minimal data.
Also London Symphony Orchestra, Michael Tilson Thomas, … - again, a spurious entity.
15. Kapela ze Wsi Warszawa and Warsaw Village Band
The latter is just English translation of the name (occurs on some album covers), this is the same band. Now albums are split between these two names. You can make WVB an alias for KzWW.
16. Nurse With Wound & Stereolab
Should just be under Nurse with Wound.
17. Michael Nyman Band
I’m not sure the two main records and one single/EP (which, as is the case for a huge lots of artists, is a main album and not single or EP, but I will create a separate ticket for this) are worth this separate category and can just go under Michael Nyman (where they already are, as MN is also listed as an artist here) - quite a number of records under Michael Nyman are actually played by Michael Nyman Band without this being mentioned anywhere in Roon).
18. Michael Nyman & Michael Nyman Band
This one makes even less sense than the previous one.
19. Om
This is this other case - records of two entities being listed under one entry.
Variations on a Theme, Conference of the Birds, Pilgrimage is one metal band (and this entry should be for it only).
Ritual Places in Bulgaria is something completely different.
Om is something still different (it mentions Om Attack inside).
Studio Rouge is an album by Stephane Wertz, nothing related to Om.
A Retrospective is still another artist, the same one as Willisau.
These are all Tidal albums, but one of the main selling points of Roon is that it corrects the horrible mess that is Tidal metadata…
20. Philip Glass, Philip Glass Ensemble, Kurt Munkacsi
Joined together three performers, should be under Philip Glass (where it is not listed).
And listed under P!
21. Philip Glass Ensemble
Listed only for a single record (while it is related to more) and with biography of Philip Glass.
In such case perhaps better to delete it and just leave the record under Philip Glass (where it already is).
22. Public Image Ltd. and Public Image Ltd
The former is the real deal, the latter is misspelled (lack of dot after Ltd), has only a single record and no data on the performer. Should be removed.
23. Steve Reich w/ Pat Metheny
Spurious.
24. Sainkho
Whatever is listed under Sainkho, should also be listed under Sainkho Namtchylak (Mother-Earth! Father-Sky! is not).
25. Salvatore Licitra, Kronos Quartet, Orchestra Of …
Another joined name, should occur under each of the segments.
26. Sex Pistols and Sid Vicious
Should be two separate artists.
27. The Sid Vicious Experience
Should either be under Sid Vicious, or at least sorted under S and not T.
28. Thee Silver Mt. Zion Memorial Orchestra
Should be also listed under A Silver Mt. Zion (or just sorted under the artist A Silver Mt. Zion, though it makes less sense) - the same band that used different names.
There is also Thee Silver Mt. Zion Memorial Orchestra & Tra-La-La Band. Should also be under ASMZ.
29. Sinfonye & Stevie Wishart
Another incorrectly joined name.
30. Sopor Aeternus & The Ensemble of Shadows
As there is an entry for Sopor Aeternus, this should be split (The Ensemble of Shadows is not an existing musical entity, just part of name that the creator of the project likes adding to the base name Sopor Aeternus), or all listed under SE, or all listed under SE&TEoS - this is the same artist.
31. Sunn O))) meets Nurse With Wound
Incorrectly joined name. Should be listed under Sunn O))) and Nurse with Wound.
32. Esbjörn Svensson
Lists (almost) exclusively albums of Esbjörn Svensson Trio - only Layers of Light is not.
33. Terry Riley. Members of the Creative & Performing …
Another spurious name, should be under Terry Riley.
And it is sorted under T and not R.
34. Tatsuhisa Yamamo
Is a misspelling, should be Tatsuhisa Yamamoto (as listed on the cover of the album).
I will have some more examples once I’m at home and connect to my network disk.
