There are artists who have passed me by for the simple reason that I wouldn't know where to start, Ry Cooder is a prime example. Others I've heard a bit and didn't like (e.g.Bob Dylan, Miles Davis). There are other artists who blow hot and cold for me but I do listen to the stuff that I like and filter out the rest, like Jeff Beck, who i think is a genius who often pushes the envelope a bit too far for me.
