FR: Search with MusicbrainzID if avail

[gerroon]

HI

I can`t be sure about this but I think that Rompr is not using MusicbrainzID to get info from the MB site.

Here is an example, I played track 7 from it but it was not able to pull any info in the MB tab. The tracks have all the neccessary MB ids created by Picard.

https://musicbrainz.org:443/release/248670a2-2f06-4203-b90f-27635d43a389

I get

"Could not find this artist on Musicbrainz" "Could not find this album on Musicbrainz"

From the metadata

artist id :9a4bb654-35c5-4c88-8460-39d5bb01aa57; 22872b62-5faa-43f3-8a45-f4386385af1d; 3a9f0e21-5796-4f04-bd4c-3deafd59ad80

Btw the gitq forum paghe is borked, whenever I try to post (I lost couple posts already) I get 400 there, so I did not have chance to query this issue there.

Rompr definitely uses the MusicBrainz ID if it is available. I've just tested it.

That specific artist id you posted there has 3 separate MusicBrianz IDs in it. I'd need to see the output from MPD/Mopidy to see if it harsed it correctly.

While that track is playing:

telnet ip.address:port

Where ip.address:port is the address of your player

currentsong

Send me the output.

In any case, requests to MusicBrains are both rate-limited and number-limited. If you have been doing a lot of requests you will have been locked out for 24 hours.

[fatg3erman]

Additionally, based on both this and the collection build debug log you sent, I have a suspicion that your player (MPD?) is not configured to output Album Artist information. This is a setting in your mpd.conf (Google it). Either that or your files are not tagged with Album Artist information. By default, RompR bases all of its searches on Album Artist information so if that's not available it won't have an MusicBrainnz IDs to work with.

You can also try enabling the option 'Display Composer/Performer in Now Playing' which will make RompR display all artist information it can find, and give you chooser bar at the top of the into panel. In that configuration it will be using the artist information.

Still send me the telnet output though, it will confirm things.

OK

I will look into the album artist for Mpd and try again. Also I use album artists,

This the ffprobe for the example track (track 7) I mentioned

As I suspetced there is no AlbumArtist field in the MPD output. Also there is no Musicbrainz info there either. I can only use the info MPD gives me.

Something wierd in the ffprobe output is that you have mutiple album_artists separated by commas and mutiple musicbrainz albumartistds, but separated by semicolons. MPD expects semicolons for multiple fields, so what you effectively have there is one artist with 3 IDs. That is never going to work.

As this is either an issue with your tags or with your mpd configuration, I'm closing it.

[gerroon]

Hi

Thanks for looking into this. I am still investigating why Mpd does not scan for the album artist. I have been using ffmpeg for Mpd, I wonder if that is the issue.

On the other hand, lets say that that albumartist field is either missing or jumbled, how about the actual Musicbrainz IDs if they were to exist in the song? They are no use this in this case?

[gerroon]

Btw, I understand what you are saying about MB IDs separated by semicolon stuff, to be honest I have seen all kinds stufff used for field sepearations from MB myself like ampersand, commas, semi colon, slashes etc.

For example here is one filled by Picard in the album artist. I realize this is neither caused by Rompr, nor its responsibility. I am just stating that one's standard does not stay true for another's.

"Mario Schiano, Paul Lovens, Peter Kowald, Paul Rutherford, Ernst Reijseger"

[fatg3erman]

With MPD (not supported in Mopidy) Try the telnet thing again but this time issue the command

tagtypes

You should et a list that looks like the following:

tagtypes
tagtype: Artist
tagtype: ArtistSort
tagtype: Album
tagtype: AlbumSort
tagtype: AlbumArtist
tagtype: AlbumArtistSort
tagtype: Title
tagtype: Track
tagtype: Name
tagtype: Genre
tagtype: Date
tagtype: Composer
tagtype: Performer
tagtype: Disc
tagtype: MUSICBRAINZ_ARTISTID
tagtype: MUSICBRAINZ_ALBUMID
tagtype: MUSICBRAINZ_ALBUMARTISTID
tagtype: MUSICBRAINZ_TRACKID
tagtype: MUSICBRAINZ_RELEASETRACKID

That's mine. AlbumArtist is there, along with the musicbrainz stuf. If it's not then MPD is not scanning for it. You need to fix that and then completely rescan all your files. If it is there, then your mpd is not capable of reading them, whcih is very odd.

The Musicbrainz IDs are no use if they have no artist to match with. In your example you have effectively one artist - "Jordi Savall, La Capella Reial de Catalunya, Hespèrion XXI" but 3 Musicbrainz IDs. Which one should I use? There's no way to tell. And in fact they're all wrong for that 'artist'.

I take your point about the tagging, but there is a de-facto standard, and it is to use semicolons.

[gerroon]

HI

Thanks for the reply.

My tagtypes is quite limited it seems :( I wonder if the Debian maintainer did not compile it wiht other options, I ll look into this.

tagtypes tagtype: Artist tagtype: Album tagtype: Title tagtype: Track tagtype: Name tagtype: Genre tagtype: Date tagtype: Composer tagtype: Performer tagtype: Disc

[gerroon]

@fatg3erman

Do you mind telling me how you were able to have MUSICBRAINZ_* tag types with your MPD? I cant find any info on how to add those , not sure :(

EDIT:

Never mind I should have thought about just adding them in the config as they look :( Sorry for the noise.

[fatg3erman]

So is it working now? Bear in mind you will have to do a full collection rescan, not just an update, for MPD to find all the tags you have configured.

[gerroon]

Yeah, I think I finally did it, I was missing the actual MB tags+rebuilding Mpd database, having albumartist was not enough I think.

Thanks for the guidelines here.
