ITunes 11 - Default Genre Artwork

Question

How do I set default genre artwork in iTunes 11? iTunes has remembered what was my iTunes 10 default grid artwork for genres, which I set by scrolling through the tile and then right clicking and setting the artwork I wanted. How do I edit this, or remove the default artwork I have set in iTunes 11?

I saw this inquiry and had a similar question about how to create a default genre artwork for a newly created genre category in iTunes 11. Following erixium and Steve Taylor1's starting instructions I discovered a method to perform this task that I thought I would share.
Create a new genre in iTunes.
Control-click the item you want in a new genre.
Select Get Info from the drop down menu
Select the Info tab
In the Genre box at the bottom type in a new name, let's call it example for this sake.
Click the Okay button at the bottom right, should be blue.
Close iTunes
Create a new Genre artwork from a .jpg file and name it genre-example.jpg
In Finder go to the Applications window, select iTunes,app and control-click
Select Show Package Contents from the drop down menu
Copy the new Genre artwork into the Resources folder
Look for a file named genres.plist in the Resources folder.
Copy that folder to another location and save a copy of it in case you make a mistake and need to go back to the original.
Control-click the file and select open with then other from the menu
Select textedit.app as the application to open it with and click the open button on the bottom right
Go to the bottom of the file and select the last 4 lines prior to the line with </array>, they should look like this
Copy those 4 lines below the selected 4 to create a new item
Change the 2nd line (in this case musical score) to the name of the new genre you create in iTunes
Change the 3rd line (in this case genre-soundtrack.jpg) to the name of the .jpg file with your new artwork that you already inserted into the Resources folder of the iTunes package
Save the file
Copy the file to the Resources folder of the iTunes package overwriting the original genres.plist file
Close the iTunes.app Finder window
Open iTunes
Your previously newly created genre should now be using the genre artwork that you selected.
If anyone finds an easier way to do this, please post.
Thank you.
