Title: Recommendations for program to replace/append multi value metadata ?
Post by: alec.tron on January 07, 2017, 04:32:51 AM
Heya,
one workflow I have yet to find a good solution for that neither Musicbee nor Foobar can do (afaik - MB: http://getmusicbee.com/forum/index.php?topic=20478.0 , For foobar I use foo_masstagger for similar things, which works mostly, but things get tricky/impossible when it comes to multi value metadata on flac files with that as well...).

I often find myself wanting to append/remove/re-order multi-value metadata; mostly in Genre or Artist field...
For a practical example - I have (on multiple files, lets's say 2 mp3s w TCOn field, queried through mutagen python module):
Genre file 1:
TCON': TCON(encoding=<Encoding.LATIN1: 0>, text=[u'Metal', u'Drum n Bass', u'Dubstep'])
Genre file 2:
TCON': TCON(encoding=<Encoding.LATIN1: 0>, text=[u'Punk', u'Drum n Bass'])


There's 2 operations I'd love to do (ideally on multiple files, which might have different and/or differently ordered tags, which complicates things further...):

1)
append value at specific position.
eg:
In the above case, I would like to append 'Rock' at position 1.
So the result would be:
Genre file 1:
TCON': TCON(encoding=<Encoding.LATIN1: 0>, text=[u'Rock', u'Metal', u'Drum n Bass', u'Dubstep'])
Genre file 2:
TCON': TCON(encoding=<Encoding.LATIN1: 0>, text=[u'Rock', u'Punk', u'Drum n Bass'])

2)
Search for a value, and inject/remove another value:
eg:
In the above case, I would like to replace/add 'Breakcore' behind 'Drum n Bass'.
So the result would be:
Genre file 1:
TCON': TCON(encoding=<Encoding.LATIN1: 0>, text=[u'Rock', u'Metal', u'Drum n Bass', u'Breakcore', u'Dubstep'])
Genre file 2:
TCON': TCON(encoding=<Encoding.LATIN1: 0>, text=[u'Rock', u'Punk', u'Drum n Bass', u'Breakcore'])


I haven't tried mp3tag and some of the other mostly mp3 editors over the last years - does anyone know of one that can do the above (on multiple files [on mp3 = fake multi value fields, and flac = true multi value fields] - which might have different tags/ordered tags even...?)

Cheers.

One of the foobar component devs had a good way & syntax to use foobars' auto-fill dialogue for correct multi-value metadata search & replace handling, in case anyone is interested to do the same.
 
i.e., use :
"Other"
and:
$replace(%genre%,', ','; ','genreString','genreString; appended genreString')

this injects "appended genreString" after "genreString" correctly as a multi value tag into mp3s as well as flac files.

What you are asking is pretty straightforward with regex.  It can be accomplished with any tagging or media player software that supports it.  Both MP3Tag and Musicbee fortunately do.  I don't know about Foobar2k because I don't really use it at all.  I'll be shocked if Foobar2k doesn't support regex.

** For adding the genre "Rock, " at the beginning of other genres (postition 1): Metal, Indie, etc > Rock, Metal, Indie, etc

Musicbee: Musicbee > Tools > Tagging Tools > Search and Replace (I hotkeyed mine to CTRL+SHIFT+R)

1) search for: (.*)
2) in field: Title
3) replace with: Rock, $1
4) search criteria is a regular expression [checked]


MP3Tag: quick action > replace with regular expression

1) field: TITLE
2) regex: (.*)
3) replacement expression: Rock, $1

** For adding Breakcore behind Drum and Bass: Foo, Drum n Bass, blah > Foo, Breakcore, Drum n Bass, blah

Musicbee:
1) Same as above
2) (^.*)(Drum\sn)(.*$)
3) $1, Breakcore, $2$3
4) Same as above

Sweet, will try it out now with Regex being available in Musicbee.
The foobar way works but is a tad cumbersome. Regex syntax is still breaking my brains though... so will see if I can make sense of the above :D
Churs.

The regex feature in Musicbee's native search and replace was there before Steven added $rxreplace and $rxsplit functions.  I started using it over a month ago to make small changes to tags while I've used mp3tag for years to make large changes.  Good luck!

On a side note, hiccup made a regex topic: http://getmusicbee.com/forum/index.php?topic=20952.0

If you have any regex questions pertaining to Musicbee, it would probably be best to ask them there in the future.
