Hi,
I just moved from ¨Music Collector" to ¨Music Connect".
On Collector, in the Track Section, I had multiple Artist for the same track, as sometimes there are “special guests” on the track.
On Connect, I can still see the different Artist on the Album view, but cannot change/add/remove it by editing.
Is it just me, or is this feature not aviable in Connect?

You can edit tracks in the Edit Album screen, then click the “Tracks” tab.
The artist field here is a flat text field, and I would recommend to comma separate multiple artists there. Like so:
Thank your for your answer, it is indeed a way of doing it.
But in Music Collector, the editing Window offered the possibility to add different Artists, and in Music Connect, on the Album section, it shows like this:
Going into the Edit Album screen, the artists are on different lines, you can see them by scrolling:
So, if the program allows it to have tracks edited by Music Collector, displayed like this, there has to be a way to achieve this using Music Connect…

The artist field in the Edit screen is a “text block” - you can arrow down it… but I would recommend just typing a comma if you manually add them.
It just works differently indeed. Not separate artists.
