We Are the World . . . Again?

Granted, the cause is noble, and also granted, it'll be hard for the re-release of "We Are the World" to make less money for the designated recipients (African victims of starvation, AIDS, and the tsunami) than President Bush originally proposed, but still, is there any reason a song the proceeds of which are earmarked for charity can't be a good song? I mean, seriously, if WAtW made $60M the first time around, just imagine what a Ben Folds or Eminem charity song, released separately, might garner!!! Is there no artist out there willing to do one EP in the name of any charitable cause, to save us from the likes of Band-Aid and WAtW?
