So here's the skinny. I've got a whole stack of files that some genius tagged like this: [http://i.imgur.com/gi5X2cK.png](http://i.imgur.com/gi5X2cK.png) Should be basic to go into mp3tag and have it batch-overwrite "various artists" in the artist field with the actual artist name from the comment field, right? However, when I load the file into mp3tag 2.72... [http://i.imgur.com/taMosUm.png](http://i.imgur.com/taMosUm.png) ...it can't see the comment field. It sees the other fields, no problem. But not comment. I've been poking at this for a bit now, trying various permutations of fucking with the tags, and mp3tag just continues to miss the field completely. It's entirely possible that I've missed a configuration option somewhere, but this seems like the sort of thing that the software should pick up by default. I dunno. Anyone got any advice? ---

You should check the settings in File\>Options\>Tags\>Mpeg Read and delete all tag versions Write only V1 and V2 If you have problems with sometimes visible and sometimes invisible fields, play around with settings for reading APE - perhaps (overwriting) data is stored there. ---

Definitely hadn't thought of that, giving it a go... ...no luck. Thanks, though. ---

What do you see when you press ALT + T or View - Extended Tags If you still don't see it, care to upload one of these file so we / Florian can have a look? ---

Now we're getting somewhere. It's apparently filed what I see as a comment field outside of mp3tag as "COMMENT MUSICMATCH\_TRACKARTIST" So that's the field that has the info I need to replace the ARTIST field with. e: Now I've got a column I'm oh-so-cleverly calling comment2 that shows that field. Now I just need to find a function that'll let me punch in the data from one field to the other. ---

Now I just need to find a function that'll let me punch in the data from one field to the other. Use an action of the type "Format value" for COMMENT Format string: %COMMENT MUSICMATCH\_TRACKARTIST% You can try the same with the function Convert\>Tag-Tag ---

I think we can mark this one solved. Thanks for helping out, everyone. ---
