Hi people, I think you are confusing guitar speed and crazy metal solos with good solos. I agree that Yngwie and Vai are maybe the most talented metal guitar players. However, I think Trilogy op 5, should be in the list. But speed playing is not related with a good solo. Confortably Numb is in a worthy #4, because is an amazing solo, and is a more or less easy solo, not very fast.
I'm a metal fan but I don't know why there isn't any acoustic solo in the list. There's life beyond metal guitar. In acoustic world there's a lot of great solos. If you want a great piece of fast guitar, you should take a look at Mediterranean Sundance-Rio ancho of John McLaughlin, Al di Meola & Paco de Lucía, or Tim Reynolds' Stream. In my opinion, Paco de Lucia is the best guitar player. When a duet with Yngwie? It could be a shocking experience.
I don't agree with many of the solos, but with the ones in the beggining of the list i do, maybe sorting them in other way.
