Indeed -- something a little like StumbleUpon's model, where a declared percentage of displayed items are actually paid placement, could work.
Payment could even be in the form of "virtual favorite points" -- ranked score is real favorites + bought favorites, though with some cap to prevent the list from becoming all paid.
(OTOH, 'favoriting' isn't hard to fake, is it? So as soon as being atop your list is economically valuable, it may become dominated by spam.)
