Ah, found here exactly my problem...
(First of all, I do my best but forgive my english ;-))
There IS a need for the ALBUM ARTIST Tag. I use a DLNA-Player and browse through my music by ALBUM ARTIST, because by ARTIST there is listed every artist, that has at least 1 Song in my Library. So, for a common Soundtrack-CD, I have 10-14 Artists, that I don`t need in this list.
But with the ALBUM ARTIST-Tag empty, the DLNA-Player will not find the Albums...
So, is there any possibility, that the ALBUM ARTIST is tagged every time, if it is equal with ARTIST or not?
In Foobar I had the same problem, and solved it yesterday by adding
-T "ALBUM ARTIST=%ARTIST%"
to the FLAC command line.
But this doesn`t work with Musicbee. For some reason, there is no chance to write a tag via command line. To exclude problems with ALBUM ARTIST, ALBUMARTIST and so on, I tried the line
-T "GENRE=TEST"
but even if the GENRE tag in the Rip Box is empty, it will not tagged to GENRE.
This is the only reason at the moment that let me stay at foobar...
