I just noticed today that in v2.46a in the lower left of the window pane, under 'Album Artist' that this actually makes a 'Band' tag.
There is a Album Artist tag and when looking at this window pane seeing that name, you assume it's a 'Album Artist' tag.
In this screen shot you'll see I underlined the names under red, showing you in the Metadata window the actual tag name it is given, 'Band'.
If this is suppose to be a 'Band' tag then then name in the left side window pane where you can add this in should be changed to 'Band' and not be displayed as 'Album Artist', this is not correct.
I personally use Album Artist tags and I know they are more popular to use, that is why I assumed this name in the left window pane had the correct tag to it and not 'Band'.
Filling in the 'Artist Album' in the left window pane, should now give you that tag in the metadata, show in this screenshot:
P.S. Sorry I didn't pay attention and see that this had been posted already. But as I said in the other post, this is not technically correct since there are both 'Band' & Album Artist' tags. If the window pane is going to say 'Album Artist' then it should be tagged that way, otherwise it should be changed to 'Band' in the window pane...
