I assume she means that she didn't download it, but copied from a friend or similar. And, the law is a bit inconsistent on whether that's legal, since it depends strangely enough on what technology you use to do the copying, which may be leading to some confusion.

Copying music on analog media for personal use from a friend is fair use, under the Audio Home Recording Act; in return, the music industry gets a kickback from every blank tape sold to compensate them. However, the AHRA does not apply (in either the fair-use or kickback portions) to copying music from a friend for personal use onto your iPod. It's not clear very many people who aren't specialists understand that home-taping is legal but home-iPodding isn't...

I think people don't get what "legal" really means. It seems comparable to all illegally-uploaded YouTube videos with "I don't intend to violate copyright" messages, which the posters seems to think exempts them from the law.

The utter disconnect between actual behavior and what is dictated by law is rather problematic. Seems like some compromise is necessary.

She does not say that those 15gb where "legally downloaded". They where copied to her iPod by a friend. She also ripped CDs and copied music from other sources, which are not categorized as "illegally downloaded". Seemingly "illegal downloading", in her eyes, is only done via file-sharing networks.

She didn't say it was legally downloaded, she said it was not illegally downloaded. Meaning she got it from a source other than downloading it.

Because it's not currently illegal to download.
