It seems to me that unless you're making money off of the copy (of whatever), there shouldn't be any intrinsic 'penalty' for owning said copy.
Sure, sure- all these legal attacks are against the distributors, but then a search engine isn't a distributor at all, as is pointed out in the article.
Heck, a lot of bands post the lyrics on their own website.
And what about broadcasting the lyrics to the masses via radio?
