The record company submits the songs/albums/artists they want to either nominate or win.
Nelly Furtado won 5 awards last night. I like her, her album is fun, but she shouldn't have won for it. It's really not that great...
Or why U2 has won 20 grammy awards for some half-assed albums (6 for How to Dismantal an Atomic Bomb.) Seriously.
Money talks.
