musicians and tracks

Hello,
One thing I faced out while was inserting manually data about a cd, is that infos in the "record Properties", tab "tracks", the content of the field "artist" is not correlated to the tab "credits", field "tracks".

For example, if the infos of the cd are not downloaded, I have to insert manually all the data related to this cd; in the tab tracks, normally there is the list of the tracks with time. If I add the name of the performer as the artis at each track, and then I go to the credits tab, and I insert the same name in the field "Person", and the "role" performer, the info in the "tracks" field is not correlated with the info I entered previously in the tab "tracks".
In the field "tracks" of the tab "credits", I see all the songs of the cd correlated to the name I entered, also if he performs only one track.
It'll be a time saving idea to correlate the field.

I hope I was clear! ;) :-/
