I don't have an Archos (and actually have never seen one) so I don't know but it's possible it doesn't force you to organize your music yourself: the post you replied to says one option was to dump a directory hierarchy.
Right. They also bundled player software for the PC that would organize things for you by metadata, and generate playlists to sync to the player that reflected that organization.
You didn't have to organize your music into directories and manage it yourself unless you wanted to.
