So a word character can be digit? Strange. I wondered why your previous RE worked as regards numbers in the beginning.

Yeah, a "word" in this space was defined to mirror allowable characters for computer program variables - alpha-numeric's plus underscore.  The developers were folks doing a lot of textual processing of computer program code (for documentation), so a \w was defined to abbreviate the oft-written RE segment to match computer program variable names and identifiers.

The expression engine is the Microsoft TR1 engine:

Why not keep it as simple as possible?

regex(if(regex([Artist],
     /#^[\[("](.*)?[\])"]+(.*)$#/, 0),
       [R1][R2], [Artist]),
  /#^[^\w\d?]*(.*)$#/, 1)

You know you're too smart if you preface that with 'simple' :P

Thanks for the info! MrC had already figured out the engine.

With global replace implemented I could substitute all references to "simple" with something more appropriate... :D
