This is kind of strange in todays market, of course you need image, but most of the sensations today are internet-born. All of them. The biggest artist out today, Drake, bubbled and gained notoriety on the internet before radio. Internet was the determinant, dude was a guaranteed success and had the biggest bidding war in hip-hop before the radio got to judge him.
Who is to say who represents Detroit today? You haven't had a big artist come out of there in forever. Big Sean is Detroit. Em doesn't rep it like that and is in a whole other bracket of legends. Just because Danny is unique doesn't mean he deserves fame for that simple fact either (you can draw up a fitting uniqueness argument for damn near any artist). Earn your shit, and be proud of what you have created. And most importantly, don't be a grade A bitch being prideful of repping your city but turning against them when you won't take attempts to build a following in the city.
It's not about the money, it's about the look. The look is what gets you those cheques in the first place and moves you on the bigger cheques. Denying a market or spitting in it's face is exactly not what you want to do if you aspire to grow as an artist.
