How can I get iCloud purchases that I've deleted from my computer to NOT show up with the new iTunes?

I've downloaded a lot of free indie music through itunes, and itunes has graciously stored all of my purchases on iCloud. The thing is, I deleted A LOT of that music from my computer, but not from iCloud, and now it's all showing up again. Is there a way I can get rid of the stuff I've deleted, without doing it one by one?
