OK, this is a serious stretch I know. I'm asking about beta software on a beta operating system, which is pretty much impossible to Google for. Here goes.
I installed iTunes on my Windows 8 machine to do some work on a friend's phone, and we backed up his music, so I ended up with all of his music library on my computer. Windows 8 seems to have generated and cached album art (which btw is a feature I despise, since I don't listen to albums ever) and now displays those images whenever I play a song in the Metro Music app.
Some of the images are vulgar. Naked people. Seriously.
Is there any way to seek out and remove these images? They have to be stored on the hard drive somewhere. I have since removed the files themselves, there is presently only one piece of music on the whole machine. It wouldn't be a problem, except that the music app displays random album art behind every song you listen to, and so broadcasts the images to the entire coffee shop. Embarrassing!
Alternately, maybe I'm misunderstanding the app. Are the images placeholders, or do they come from the store over the internet? If I can't control them at all, I simply won't use the app.
