Re: Band\\Band

You can use the ID Tag Processing DSP effect to remove the Band ID Tag.

Re: Band\\Band

I have the same problem with Band, which I think is a standard ID3V2.3 tag. I don't want it doubled or wiped out - is there a solution to not have it doubled without wiping it out? Wiping it out it out still forces me to re-write it in Mp3tag, so it feels like wiping is no better than the original doubling problem.

Whatever we do, is this just a temp solution until dMC is fixed? Is my assumption correct that this is a bug? thanks

Re: Band\\Band

There is no bug as far as I can see, in that you have 2 album artist tags when there should only be one.

Re: Band\\Band

I don't know about the first poster, but in my case I have a Band tag with a single entry in a flac file, I convert from flac to mp3 and do nothing else, and I end up with a Band tag in the mp3 file with two entries (original entry duplicated). The behavior I expected would be that all flac tags would be brought over to the appropriate tag for the mp3 file, without any drops or duplicates. The rest of the mp3 tags look OK. This happens for all flac files that I covnert to mp3 files.

Still feels like a bug, but please let me know if there is something unclear above.

Please email one of the flac files:

With a link to this thread.

Re: Band\\Band

This issue is with mp3tag displaying, in that:

Your FLAC file has 2 tags:

album artist and BAND set to the same item.

On converting to mp3 the album artist tag is mapped into the ID3 band slot, where as the BAND tag is written as a user comment of band. The mp3 file has the same 2 album artists tags that the flac file had. There is no need to have BAND written to the flac file.

Re: Band\\Band

You are absolutely right. I made bad guesses on how dMC mapped things across the Vorbis slots, ID3 slots, and dMC tag field names, and then made bad guesses in how Mp3tag mapped things.

Thanks very much. I would never have had the patience to figure this out.

I agree. After looking into this further, I realized that putting "Band" into .flac files doesn't help anything. It was the act of putting "Album Artist" into .flac files that helped. When I put "Band" in a .flac file in mp3tag, it goes to a useless /BAND/ tag, and dMC is just faithfully copying it to the converted file. Mp3tag is displaying this superfluous tag appended to /TPE2/ in "Band", and it's not a dMC issue at all. Part of the confusion is due to mp3tag mapping "Band" properly for .mp3 and .wma files but not doing this for .flac files. However, it is possible to set up a custom mapping from .flac's /ALBUM ARTIST/ to mp3tag's "Band", such that one can use "Band" throughout mp3tag, yet still read/write the correct tags to the files.

I wish I could piont a finger at someone or some application and demand a "fix", but I can't in this case

.

While digital music applications have advanced dramatically over the last few years, data standards have not, and I feel data quality or the lack thereof is soon if not currently the constraining factor on wide music lover use of sophisticated applications like those built by Spoon and his team.

We need another attempt at a true digital music tagging standard. We could put in the IEEE pipeline and wait a decade, or we can hope that a few leaders (Spoon, Florian, Alex, the original ID3 folks, providers of the major metadata sources, I suppose the Foobar folks although I am disappointed in their ID3V2.4 jihad) can collaborate on something that simplifies the current tag mess. I'd also try to invite Microsoft and Apple, but not wait for them to come along if they see parochial interest in maintaining the status quo.

I don't care what any tag does or what it's called, as long as it does the same thing and is called the same thing wherever I take my music.

Anyone agree? Can we instigate a user campaign for a few self-designated leaders to head up something like a sourceforge project?

I can offer little more than an opinion that this should be done. I'm a management-type, not a developer. In that light, I can anticipate all the reasons why this can't be done, or isn't worth it. I hope it can and is.

Re: Band\\Band

In dBpoweramp, for album artist I use the 'Album Artist' tag.

I also have in dBpoweramp Configuration Advanced Options:
Vorbis Comment Mapping 7: Album Artist to AlbumArtist (I believe this is the default setting)

So, in MP3Tag the album artist for flac appears under 'AlbumArtist'.

In MP3Tag the album artist for mp3 files appears under 'Band'.

Yes, this is a little confusing but seems to work of for me, I just have to remember which file format I am editing.

NB. flacs are streamed to an OPPO BDP-83 SE via Asset, mp3s are imported into iTunes for use with an iPod Classic 160GB.

Re: Band\\Band

...you would be lucky to get FLAC to define a standard for 'Album Artist', atleast in mp3 BAND is the defacto standard for album artist.

**biggles** · October 29, 2010, 12:45 PM

I noticed that immediately as well when I tried to find out how Vorbis Comments align with ID3 frames and various application tags.

I apologize if you've done it already and I failed to find it, but if you haven't, could you please post a table that shows the default mapping of dMC tag names to ID3 frames and Vorbis Comments? This would be very helpful in understanding how things work today, and will certainly reduce the number of posts I write and make you read!

I find the Mp3tag table very helpful - perhaps use a similar format:

Tag Field Mappings – Mp3tag Documentation

http://help.mp3tag.de/main_tags.html

Overview of all available tag fields, their names in Mp3tag, and how they are mapped to the internal structures of the different tag formats. Mp3tag is the universal Tag Editor.

Thanks again for the great support!

Re: Band\\Band

Yes, that's all I can find that relates to any kind of mapping. But the information under Configuration does not contain comprehensive mapping to ID3 frames for mp3 files. For example, I can't look at this and figure out that dMC maps its Album Artist tag to the TPE2 frame, or figure out what dMC tag, if any, maps to the IPLS frame.

Even when I look at the best list of dMC tags I can find (under CD Ripper's MetaData options), I can't find information sufficient to build a comprehensive table of what dMC is mapping to what. When I look there for example, I can't figure out if Orchestra is mapped to TPE2 or is written to a TXXX frame.

Sorry if I'm missing something, but I still think a comprehensive table will reveal a great deal of valuable information to help understand what is happening and help users convert tags between formats and other applications.
