I don't know. It depends what you mean by over-rated. He has some idol fans. I like about 10% of his work. The same with John Frusciante. But that 10% is the best music in the world. True artistry. Original. And that 10% can change depending on the mood because the work is so deep and varied. But, yeah, for sure, there are some recordings just not on my wavelength and never make it into that 10%... and maybe I do consider those 90% bits over-rated, and the 10% I like for the mood I am in at the time under-rated.
