Your money's worth is the saving lives bit. The music is the carrot.
wait wait, you cant have it both ways. if it really is "a profit oriented project and not a charity", well then there better be a product that is worth the money. if it's about giving money to save lives, and not about the actual product, then yes, it's a charity.
i don't think bono wants you to subscribe to this service just to give money to needy people, that's kind of against the whole principle of the thing.
