If by smooth, classy, and heartfelt you mean dry, repetitive, and feel-less, then yes, Santana is all of those. I say he is feel-less because his solos are all the same damn concept. Playing a spanish scale over a blues backing...whoopdy cock. "Feel" my ass, Santana can bend all the notes he wants, REAL feel is writing a solo that catches your ear, drawing you to the next note naturally with the appropriate musical devices. Santana has yet to write more than one solo, so I guess we can't technically rate him as anything but boring.
