How to delete artists form connect

Been poking around connect and there is only one artist on the list that I am interested in using connect for. I do not need U2 and I certainly don't need them twice. While I do listen to Avril Lavigne on occasion but I don't need to connect with her. Twice.

I want to remove artists and possibly add others if available. I do not want Apple guessing who I want to connect with. Apple has never ever guessed anything right about me and I want to be in control.

And yes I just admitted to listening to Avril Lavigne.
