Emby Server is creating a music artist called "|"

[echoxxzz 22]

This unusual behavior started after I began tagging my music with Musicbrainz data using Picard. 

Picard creates an extended attribute called "Artists" that Emby Server appears to read.

The problem occurs when the "Artists" tag contains a forward slash character like "AC/DC".

When the "Artists" tag contains a forward slash character I get a second artist called "|".

I setup a clean Emby Server with just one music file and was able to reproduce the problem all the way back to Emby Server 3.6.0.

I've attached a sample music file for Luke to import and recreate the issue.

AC_DC - Back in Black - 01 - Hells Bells.mp3

Hi there, have you checked the tags embedded into this audio file?

[Happy2Play 9785]

I get the same thing.  But have yet to figure out why, but the database shows the "pipe" for all tracks but not folders.  I just ignore the empty Artist in my case.

[Luke 42086]

I think i have this resolved for the next release. Thanks.

[Happy2Play 9785]

Appears resolved in 4.2.0.11.

 

Did a Refresh-replace all on my Music library and the "|" artists is now gone.

[echoxxzz 22]

Confirmed that it fixed the "|" artists for me as well.

Unfortunately, I found another character that is causing problems.

If the Artist, Album Artists or Artists tag contains a "|" then you get several artists and album artists.

For me this happens for the artist "M|A|R|R|S"  (Musicbrainz ID = 13176bb9-9a3a-48ae-b05d-75a0bb668d01)

I end up getting five artists and five album artists called M|A|R|R|S, M, A, R and S.

I've attached a sample file tagged using Picard using Musicbrainz data.

 

And this problem also causes the jumplist to disappear so I can no longer navigate by artist name quickly.

Removing the | the tags fixed all my problems and the jumplist is back.

That is a special case that I guess would have always been an issue. We could either just stop splitting on |, or add that as a special exception. @@ginjaninja any thoughts on that?

[Happy2Play 9785]

I think there would have to be some sort of whitelist so uses can add these special situations with Artists like this.  I believe there was another topic around here with "/" in the name also.

[ginjaninja 605]

stopping split on '|'  will be an issue for the casual user as its a common splitting character for other software and probably in general use.

a whitelist of 'artists with splitting characters' sounds good, i suspect even the largest libraries wouldnt exceed a handful of such artists.

Emby could distribute the common ones as standard (the forums could crowdsource this info perhaps) and the user could complement with their own.

[echoxxzz 22]

I don't know of any other artist with a | in their name. Maybe not worth fixing and I'll just modify the metadata.

[Luke 42086]

For now we can just add a special exception into the server for this artist name.
