duh...there are still a lot of artist that wasn't included in the recording, maybe some had been invited and weren't present, but other artist like rihanna, kelly, mariah, and whitney were not invited and i'm pretty sure they would love to take a part in it..... i think those who were not included be better do their own version of we are the world and i'm pretty sure it would be much greater because those who were not there are great artist that can give justice to the song than some who were there....
