Yes, yes, a million times yes. What's the point in a top 10 list that just vomits back the stuff that literally everyone and their mothers already know? Sure mainstream artists can be good, but out of the slew of music that comes out each and every year are they really the best too? Is the invisible hand of the market that good at picking our "artists"?
