Nope. The music I like doesn't/wouldn't ever get played by MTV.
That doesn't mean it's all obscure, either. Take Kraftwerk for example. They're legendary. A bunch of German guys who pioneered electronic music. Everyone from the Chemical Brothers to Madonna owe props to 'em.
Then of course there's the likes of the Violet Burning. Who have been around indepedently for 15 years and are successful in their own right, but will perhaps never get recognition from the mainstream industry.
Sorry to hear it's happened to you so often, though. I know of very few bands who've permeated pop culture and not been in some way influenced by it... so I can see where you're coming from.
