iTunes, Artist "also appears" on mockup

So since I use iTunes almost religiously, there's a feature I'd really like to see, especially seeing how I listen to a lot of rap and these guys are featured all over the place. So, without further ado:

Please keep in mind this was a VERY quick and dirty mockup, would still like to hear your guys' thoughts. Maybe it will even get some traction. Someone in Cupertino has to listen to rap ;)
