You should not hard code for the specific property `artist’.

You cannot use dot notation if the property name is in a variable.

No, but you can post the code you have tried and ask questions about the parts you are having trouble with.

Posting a solution isn’t going to help you learn much, and besides the hint page already has solutions if that is all you care about.
