That is the exact sentiment that has led me to almost entirely stop exploring the power/progressive metal genres, I find it almost impossible for a new band to make an impact worth considering them over any of the bands I already listen to. This is to one extent, or another true, for all the met sub genres. I enjoy, but most obvious, in the realms of power, traditional, and thrash.
