Just wondering if they actually collect any data? What get's sent to Apple? Can you get in trouble if they found out you illegally downloaded a song? (come on, we've all done this at least once) I want to subscribe but this is just all confusing. I have a big library (15k-ish) and they're all mostly 320 kbps CD Rips. Does getting iTunes Match mean I can listen to them (the one's that it actually finds) anywhere?
