What does it make of a person who appreciates different types of music genre? Nothing. The person just knows how to appreciate good music from whatever genre it belongs to no matter if other people consider said music as good or not.
I am one of those who are not fixated on one particular genre only, like some others who patronize rock and roll music, for example, only or above all other genre. If an artist sounds unique, with a twang that gets my attention, then the artist must be very good and/or versatile.
