Mp3 tag to VLC/Google music Album artist tag to last.fm scrobbles

I think this is a very specific problem that cannot be addressed but I will give it a shot if there is a solution I am unaware of. When I play an mp3 with different tags for artists and album artists, VLC and Google music sends the artists tags as album artists as well. What can cause this?
Is it because these apps read ID3v1? but not v2?

id3v1 has no albumartist.

The rule to get albums correct is to fill ALBUMARTIST, ARTIST, ALBUM, TITLE and TRACK.

If you are not sure if this is caused by V1 tags, I am sure that you can safely remove V1 tags as they usually contain less data than V2 tags.
