Great quiz! 19/50--Very tough, especially the states of Middle America. Interesting how closely certain acts are associated with a certain state (Dolly Parton for Tennessee and Beach Boys for California) and some are just not matched at all to their state (Bill Withers for West Virginia? Slipknot for Iowa???)
I tried to include ones that are, let's say at least in the Top 5 best known artists in their state, I hopefully succeeded at that
