well, since I got into it about 13 years ago, definitely. Lately though, not so much, well, nothing tr00 anyway - and that's not elitism, that's just the fact that 98% of stuff blowing up right now has a huge 'catch' to it which is amplified somehow in the perceptions and tastes of the mainstream that buys it. Examples... even though Blind Guardian, Firewind, and Rhapsody are also pretty "big" here in the USA along with DragonForce, they still have a certain glass ceiling because the songwriting is simply..well, better, and unreliant on a narrow crutch like 'shredding'. Death metal is always around, but a good quarter of the buying base is buying because of the 'brutality' and 'sickness', regressing the common perception of the art form as a whole on a continual basis. A lot of the better underground bands are not making the same inroads due to smaller labels and budgets, but there's also the simple fact that less people latch on to the stuff, for one reason or another.
But as I said, it's not every band, and we've still made good progress with things in general, thanks to mp3.com and now myspace...there are still tons of cool bands in the CD store at the mall that never had a chance of being there 5-6 years ago. So..
