Tag-Tag $replace of double backslash

[PeterleB]

The artist tag contains "Schürze\DJ ROBIN\Königlich Bayrisches Vollgas Orchester".
I want to replace the "\" with another character like "&" or "-".
$replace(string,from,to) ->
$replace(artist%,\,&) returns "Schürze".
I need the full string without backslashes.

See e.g.here:

Cannot replace double back slashes ( \\ ) using simple Replace action

I tried a simple replace where I was trying to replace a " \\ " with ", " but the action does nothing. I assume this has to do with \\ signalling separate fields. Is there a way to get around this? I thought I had replaced " \\ " before, but I cannot find anything in my notes.
