...when did that ever happen? The post-Napster-but-pre-BitTorrent era (coincidentally, the same time-period as the BonziBuddy-era) was when Morpheus, KaZaA, eDonkey, Limewire, et cetera were relevant, and they got-away-with-it, in-part, by denying they had any ability to moderate their users' file-sharing; there was no "submitting of every song" to an exclusion-list because there was no exclusion-list or filtering in the first place.
