Tidal duplicates album artists

[phw]

For some reason Harmony started to get double album artist credits from labels, where it ends up with the album artist being "The Artist & The Artist".

E.g. see https://harmony.pulsewidth.org.uk/release?tidal=478959100&spotify=3JHkIBKfmzHOXPrmcDEHno&gtin=4065629759803&deezer=&itunes=&region=GB&ts=1768197015

But in my tests this happened with all releases from Tidal. If there are multiple artists on the album it duplicates each of them, e.g. picking the random https://harmony.pulsewidth.org.uk/release?tidal=16533576&spotify=0DJcrAJy2n8luCPGvxM5sl&gtin=8717306944908&deezer=&itunes=&region=GB&ts=1768199545 gives the credit "Arctic Moon, Arctic Moon, Truewave & Truewave".

I haven't yet checked what changed in the Tidal API to trigger this.

I checked the API release response. The artist are returned twice in the included section. The entries are exact duplicates. Actually looks like a mistake on Tidal side, but best would still be for Harmony to filter it.

There is another problem, though: for https://tidal.com/album/16533576 the track artist Armin van Buuren is shown as "unknown artist". There is also no entry returned in the API, and hence no name available. But this maybe is a data availability issue on the Tidal side we cannot do anything about. The artist URL https://tidal.com/artist/3521263 shows "Page could not be found". Maybe it is a region thing.

Yeah, that was #173, which I handled with a placeholder and an error message. Now that I see your example, we should probably ensure that the same error message is not repeated for each occurrence.

Maybe Harmony should just deduplicate everything. Deezer can also have duplicate artists: #183
