Since I'm adding many psytrance releases recently, I also want to set the relationship 'remix of' correct.
I'm wondering, how to choose the 'original' track of a remix. Often the same track of the original artist appears on different releases, e.g. on an album and on compilations, but with slightly different running time. (I expect all should belong to the same 'Work' and I think I can't make this relationship to a Work.)
But how do I choose? Should I take the recording that first appeared? Should I don't touch it till the artist fills it himself?
