Nice of you to self-quote, I'd never read that old blog post.
I do find this sentence quite unkind towards Dave Matthews though: "Milan Kundera is the Dave Matthews of Slavic letters, a talented hack, certainly a hack who's paid his dues, but a hack nonetheless". If a hack is talented and "pays his dues", he stops being a hack, surely? What does it take to be an accomplished artist then, apart from being David Bowie?
Your question cuts to the heart of what makes art art, and I can't answer it. But hard work and perseverance doesn't make a hack into an artist; it just makes them a more prolific hack.
