Didn't you participate in a thread that deals more or less with the problem of lists with a slash in them?
And to be honest: the swapping of names ... does it really make sense? There are so many exceptions that the swapped names in the end do not ease the access to the artist.
Any decent player will search for artist name parts so it does not matter which structure the name has.
In which field do you want to swap the names? I hope, only in the ~SORT fields as otherwise it will become a strange thing to look for Uriah Heep under "H" but Pink Floyd under "P" - because I guess that you will only swap name parts for names that look like first name, last name.
And would it make sense to see, "Stones, Rolling", together with "Stone, Joss".
The only exception I see is the removal of articles for names where the artists themselves did not keep a straight line, like "Beatles" and "The Beatles".
Uh, just found a nice name: East 17 - that would be sorted to "17, East"?
It does not make sense to me.
And if you say, well that is an exception that stays as it is - what qualifies exceptions? So it would need complicated rules as to when a name is swapped and when it isn't - when the simplest rule would be: take it as the artist calls himself.
