At BEIC, to test the Wikidata ontology and the feasibility of collaborations on music data, I was assigned a seemingly simple test: add in Wikidata all the data contained in https://en.wikipedia.org/wiki/Brown_Sugar_(The_Rolling_Stones_song) .
Turns out things are not so simple: * the Wikipedia articles, from an FRBR (https://en.wikipedia.org/wiki/FRBR ) perspective, often mix multiple levels or even all of them (song, recording, album, single, edition of the single) which on Wikidata need to be separate items, but the split is not obvious: https://www.wikidata.org/wiki/Special:WhatLinksHere/Q21887964 ; * I was unable to properly add information on per-country hit list position.
Please give a look to the items I linked, to my https://www.wikidata.org/wiki/Wikidata:WikiProject_Music updates and to the open questions I added in https://www.wikidata.org/wiki/Wikidata_talk:WikiProject_Music .
In particular, I think librarians will be interested in this proposal for a "performance of" property, which (like the existing "edition of" property) could benefit from being framed in a FRBR perspective by someone more versed in FRBR. https://www.wikidata.org/?diff=287456096

Rather than FRBR (which isn't that great, even for books), I'd look at how MusicBrainz and/or Freebase do things (they're pretty closely aligned, I think).
Composition https://www.freebase.com/m/048bf9 Single https://www.freebase.com/m/01hmyv3 Sticky Fingers album https://www.freebase.com/m/01hmy3x primary album release https://www.freebase.com/m/03436qv Brown Sugar track on that release https://www.freebase.com/m/0l44n1g Brown Sugar recording which appears as that track on the album https://www.freebase.com/m/0frvqbn
Each of these, except for the release-recording connector, is linked back to the corresponding entity on MusicBrainz, so you can see how they present the same information.
The advantage of following a schema like MusicBrainz is that you get to take advantage of the knowledge of domain experts who've thought deeply about how to structure this information. This is something like the third major revision of their schema, over many years, so a *lot* of thought has gone into it.
The advantage of the Freebase view is that it shows how the music specific piece integrates with other general knowledge elements and external information sources like Discogs http://www.discogs.com/release/1489020 in a manner similar to what Wikidata would want to do.

Hi Federico and hi all, FRBRoo https://en.wikipedia.org/wiki/FRBRoo - today at version 2.0 - introduced the concept of "Classes of Work" for the Performings Art. You can find the text of guidelines on IFLA website http://www.ifla.org/node/9453 and a cheat sheet on CIDOC website: http://www.cidoc-crm.org/frbr_graphical_representation/graphical_representation/expression_manifatation_added_value_chain.htmlas you can see, the relations "performed" and "was performed in" are expecteded between "Performance" and "Performance plan". A quick and clear explanation of this concepts is here https://www.researchgate.net/publication/252888336_FRBR_OO_a_Conceptual_Model_for_Performing_Arts (in particular, pp. 6-9). In conclusion, I think that the property "performance of" is necessary but, first of all, it's need to define when to use this property. Happy New Year! Chiara
