I am guessing he is talking about the 'Store' version. (burn that one with fire)

Yes, probably the Store version.
Exactly, sorry for not being clear on the OP.
I'm not sure that I understand all that you said, but:
If it's about the Album and Tracks view, set it to 'detailed list' instead of 'compact grid'.
That should allow you to specify fields. (such as play count)
Didn't find the option here yet. But thanks for the tip.EDIT: Okay, i think i found the screen i wanted to mean. is this one of this image i found in another topic on the forums:

EDIT2: The issue was just a matter that i was adding the tabs (Artist, Featuring Artist) based on the Music item and not Music Explorer one:

I've noticed that while i can add multiple tabs based on 'Music', adding multiple 'Music Explorer' causes what i can call "redundancy", i mean any change made in one tab ends up going to another of the same type.
