Gee, all you "serious musical types" sure know how to suck all the fun out of something which is supposed to be fun. Music, that is.
The more technical amongst you will say, "Hey, guitarrist X is so much better than guitarrist Y because X has a broader range," whereas others, such as myself, will just say, "Hey - this solo kicks arse!"
And just because someone can play "Mary Had A Little Lamb" in fifteen different ways doens't mean much. Some "limited" bands, such as Nickelback, are doing just fine doing what they do now - catering to a specific audience and playing the way they do. And I've heard a bit of Chad Kroeger's solo stuff, and he's not that bad - proving that he's not as untalented as some would claim.
Plus we all know Angus Young is a God. 'Nuff said.
