Keep in mind that even though I selected "mostly from CD and some downloaded" this still dosen't mean it's illegal. My Mark 1 introduced me to the wonders of MP3.com, and I have several downloaded and legal songs from that site. Also, I have a TMBG album that I bought online and downloaded directly.

The "downloaded a few" choice will probably be higher then the "all from my personal CD collection", but it's definitly not an indicator of how many tracks are illegal.
