Firstly - You'll need to come up with a few new laws for the music world:
Thou shall have Susanne Boyle carted off to an old folks home so she can't release anymore number 1 albums.
Thou shall not have people in the charts with unclear genders - co
cks in frocks. i.e Lady Gaga.
Everything that will be released has to go through the king and if he says so, it will be released. If he doesn't it will be scrapped.
Second - If you choose to, you may pardon artists or genre's for past offenses. You can also declare war on artists or genre's.
None. I'm a ruthless king.
Finally - Since you're in charge now, every musician on earth is probably gonna want you. So now you need to pick who will be the queen/king to rule by your side and wear your crown.
If you can have past artists...
If you can't...
F
uck off I'm the king
