LOL - I thought you were a school kid too shredder! You just have that mentality, and a child like way of putting across your points.
Its not about songs needing guitar solos. Solos, good mid 8s, half-time sections, double time outros etc add variety and depth to songs.
The new metallica album is a a bunch of random riffs thrown together! It as tho every song is based on the chromatic scale. Its utterly awful!
