What about stuff like the godfather theme that slash plays? That's technically I guess a big guitar solo, but it sounds damn good. Or what about classical pieces transposed onto guitar, such as pachabel's canon, or that paganini 5th caprice thing at the end of crossroads? Are they classed under "look at me I'm better than him" or could it be that someone thought it might sound, like - I don't know, nice maybe?
