Hide the Tag for Album Artist in Track Information
I don't think it's a good idea to show the album artist tag on top of the artist tag (especially in fullscreen mode). It clutters the screen with duplicate information and makes that line longer than necessary and therefore harder to read and grasp the information you are really interested in (knowledge of the interprets of the song currently playing).
Here are some examples where this behaviour makes it more confusing to understand what part of the line actually is suppossed to represent the artist (comma seperates the artist from album artist tag):
In my opinion something like 'Various Artists' should not be presented for a specific song playing. In providing this info we don't learn anything worthwhile but overwhelm the reader and bury the most interessing part in the presentation. It would be much easier to understand the actual performer with the album artist suffix missing.
Removing the album artist tag is not an option, because the tags for all of my music are sourced automatically from the MusicBrainz database which is probably the most comprehensive encyclopaedia for audio. Futhermore, some music players like the one i'm using on android need this tag to group compilations (otherwise the same album is split up many times for every single artist).
