trying to find set Itunes compilation with
SetAttr META
is there a full list a tags for SetAttr META tags
a i would also would like to automate all disk # on folder name eg CD1 CD2 and so on
i can't see Itunes compilation can this be added ?
tag code COMPILATION value: 1
I would have thought you'd want the discnumber tag?
iam trying to do 2 things
1 add the Itunes compilation Tag
2 add disk # baste on folder name eg cd1 cd2 cd3
I don't think Opus knows the iTunes compilation tag.
I would love it if Itunes compilation could be added in an update 
please
the music program i use, " Musicbee" . uses Itunes compilation to set album to compilation for Various Artists Albums
I would love it if Itunes compilation could be added in an update
please
That's a fairly big wish. Even the Grandmaster of Tagging can't write it:
https://metacpan.org/pod/distribution/Image-ExifTool/lib/Image/ExifTool/TagNames.pod#QuickTime-Tags
Or do you mean something different? There is a COMPILATION tag available in Mp3Tag, maybe worth checking.
2 add disk # baste on folder name eg cd1 cd2 cd3
If the foldername is exactly right, you could use this
SetAttr META "discnumber:{filepath$|..|nopath|noterm}"
With a script you could apply string operations on the foldername.
SetAttr META "discnumber:{filepath$|..|nopath|noterm}"
is not working for me if I select CD1 CD2 folder ?
I'd expect discnumber to be a number (1, 2, 3, etc.) not a string ("CD1", "CD2", "CD3", etc.)
You need to select the mp3 files. The command will then set the foldername as the discnumber. Opus will actually strip the non-digit characters, so even a foldername like My awesome Album CD1 (so cool) works without scripting.
cool it works now ... (once i know how to use it )
one small thing can it be set like this 1/3 2/3 3/3
yes COMPILATION will work for the Itunes compilation in mp3tag but cant set in in dopus with SetAttr META ?
yes the disk are # (1, 2, 3, etc. in the tag) but for folder names i use CD1 CD2 CD3
This might be worth taking a look at:
Towards the end it talks specifically of Part of a Compilation and states:
COMPILATION:
Syntax: Either enter the value 1 or delete the field
Note: Unofficial field that is only used by iTunes/iPod to mark albums as sampler.
one small thing can it be set like this 1/3 2/3 3/3
Even if there were an easy way to compute the '3' it would still require another tool, since (as we just found out) Opus only writes numbers.
Use Mp3Tag and do it manually. Better yet: Ditch the whole discnumber shenanigan. It's 2019, why organize files by CD?
cant set in in dopus with SetAttr META ?
Nope. Opus can't even read it. ExifTool can't write it either.
Use Mp3Tag: Drag all your files into Mp3Tag, select them, hit 'Extended Tags...' and set 'Compilation' to '1'. Done. Define an 'Action', if you need to do it frequently.
why organize files by CD? because that is how the artist recorded the album in the first place ?
most tagging software can read and write disknumber as 1,2,3 or 1/3 2/3 3/3 and dopus can display 1/2 2/2 3/3
and disknumber is use to keep albums together so you can use one album name for all cds in a box set or what ever
also using 1/3 2/3 3/3 lets you know how many disks in a set
Opus can write X/Y style tags as well.
