"Artist" as a list field could cause problems with the internal automatic Album Artist logic, online databases and many other programs & player devices. In my opinion it is better to not change the behavior of the most common, traditional "CD database", fields. I have used a custom "Contibuting Artists" list field for this purpose.
Well, Artist (and Genre) field not accepting multiple values is the main problem I have with JR, as it's a keystone of my library organization (I'm quite new to JR, but I didn't start yesterday with PC music).
Now, reading old posts on the forum I understood, please correct me if I'm worng, that this feature will never be added and the main reason against is "compatibilty"...
At this point I'm completely lost, as most programs use multiple value for Artist and Genre (even iTunes!); moreover I see a compatibilty issue in beeing forced to use optional fields for a main tag, breaking the portability of the library; finally, a multi-value field is backward compatible with single value by definition and not the contrary, if you don't want/need to use multiple values you may simply ignore it...
So to speak, I'd be perfectly happy to have the "Data Type" dialog unlocked even with a pop-up saying: "WARNING! This function is not recommended, not supported and you're using it at your own risk!"
But of course I'd miss something; as I'm not a programmmer it's very possible.
Can somebody explain me what exactly is the compatibility problem with Artist (and Genre) multi-value field?
I'm ready to change idea if a get a resonable explaination.
