This usually takes years and tons of music "processed" by you. I mean not only listening to it, sometimes it is useful and interesting to know how musicians record their music, why they do it exactly this way, and what is more behind it. Rock/metal is a nice field to dig in this regard, just don't limit yourself to a single subgenre, try different ones, explore the musicians' backgrounds and so on. Intelligent musicians produce interesting music, interesting music develops taste. I see it this way.
