Either speakers are accurate or they're not.
The picture is rather less black and white than you paint. I suspect most audiophiles will agree that speakers vary by degrees with none being "accurate" when compared to most electronics.
I've never understood trying to match speakers to particular types of music
I assure you it works. Quad ESL's at low SPL's with soft acoustic music can be sublime...but they won't play rock very well. Some audiophiles have several systems that are suited to various genres. In theory, this may be the "best" option - multiple systems with each designed around a particular genre...
