"group multiple disc set" combined with compilation albums

[seerdekens]

It seems "grouping multiple discs into 1 album" is working correctly for regular albums of one and the same artist, but not for compilation albums.

For example the White Album of the Beatles: 2 discs are correctly put into one album.
here I have the following directory structure:
Beatles\whitealbum\CD1\01 - Back in the U.S.S.R..flac
Beatles\whitealbum\CD2\01 - other song.flac
'album tag' is for every song the same. I don't make use of the tag 'album artist'.
I use an additional "discnumber" with value 1 for songs of CD1 and value 2 for songs on CD2

I did the same for another 5 disc album, but all songs are from various artists.
Strange thing is, when I view properties of the song in Squeezecenter I see for example
song x --> disc 1/1 where it should be disc 1/5
song y --> disc 3/3 where it should be disc 3/5
This works correctly with the Beatles album

I have the following settings:
- Group compilation albums together
- List albums by all artists for that album
- Treat multi-disc sets as single album

Anyone knows how I can get this working?

what exactly is wrong as you see it? just the 1/1, 3/3 thing? (instead of 1/5, 3/5)

How many albums did SqueezeCenter create from this one album? Double-check your album name tags on all tracks and make sure they're all identical.

[seerdekens]

5 albums
I already checked the album tag (by putting all songs in MP3tag). It's identical for all files.
I even did a rescan of the complete library.
PS: the album name is "100 op 1 De Beste Belgen".

[JJZolx]

What does your directory structure look like? Same as the Beatles album, with folders for CD1, CD2, CD3, CD4, CD5 all in one album folder?

[MrSinatra]

i'd also like you to state just what is wrong?

Yes, this is the complete path
\volume1\music\catalog\FLAC\Various\100 op 1 De Beste Belgen\CD1
\volume1\music\FLAC\Various\100 op 1 De Beste Belgen\CD2
and so on

I've put all my compilation albums into the directory
\volume1\music\FLAC\Various

'treat multiple discs as 1 album' is appaerantly not working for some albums.
As far as I can see it's working correctly for albums of 1 artist, but not for compilation albums (various artists)

[MrSinatra]

my guess is this is b/c of the "greatest hits" logic.

yes, your albums have the same album tags, but differing artists in differing folders, so you get 5 albums representing your 5 folders, where SC assigns them a value of "Various Artists" as a substitute for an AA tag.

i would try setting a comp tag =1 and setting an AA tag, altho be aware that SC has a bug where it hides music with AA tags = Various Artists without a comp tag.

So I'll add tags with the folling names and values:

name 'comp'
value '1'

name 'AA'
value 'Various Artists'

would it also change a thing if I put all files into 1 folder ?

Thanks

i was using shorthand, i don't know exactly what flac wants or how it works...

its going to be something like this:

COMPILATION=1
ALBUMARTIST=Comps

hopefully Jim (or someone) can clarify and/or say if i'm barking up the wrong tree.

edit: if you put all 5 in one folder, that might also fix it without the extra tags, but honestly this should work without you having to do that. (i wouldn't want to have to do that)

it certainly seems there is a bug or two in this situation.

ok thanks, I'll try this when I'm at home.
I'll let you know

I put together a little test library and was able to duplicate this. See this bug report: https://bugs.slimdevices.com/show_bug.cgi?id=7869. In particular, comment #6.

The workaround is that you must add a COMPILATION=1 tag to files in a multi-disc compilation if you want to group the discs into a single album.

Edit: You don't need to add an album artist.

[seerdekens]

It's working perfectly now with the compilation=1 tag.

I didn't configure the AA tag, because on http://wiki.slimdevices.com/index.php/Compilations I read the following:
"No matter what the individual track artists are, if there is a common ALBUMARTIST then the album is not a compilation."

Thank you very much JJZolx and MrSinatra

[MrSinatra]

i think thats true, but i also think the comp tag will override the AA tag when both are present.

there is definitely some kind of bug here though, or contradiction, b/c my understanding is that the VA detection logic essentially assigns an AA value to the SC DB of "Various Artists" if it detects no explicit AA tag and an artist mismatch.

so the beef then is when greatest hits logic comes in and says "same album name with different folders = separate albums" ...it overrides in this situation.

so a comp tag alone is enough to fix it, it then seemingly overrides GH logic. but what does it do different that the VA logic doesn't do?

anyway, i wonder if an AA tag alone would be? and/or what would happen if the AA tag was = Various Artists

and/or where the album[s?] would get sorted to if it had both AA and comp?

(all this begs the question of what do you do with two comp CDs that are unrelated yet share the same name?)

also...

i am curious as to if your 3/3, 5/5 issue is corrected? i am assuming it is. my guess is that happened b/c again GH logic saw all 5 as separate and distinct unrelated albums, and simply used your value.

personally i don't like these logics, (the VA one anyway), and would like the option to disable it for a much different system of user defined string recognition and VA album handling/ID.

[seerdekens]

disc numers are now indeed correct:
so Disc: 3/5 for example (were it was 3/3 before)
