Jay-Z, Lil Wayne, Paul McCartney, Radiohead, T.I., Justin Timberlake and Kanye West have been added to the lineup of performers at the 51st Annual Grammy Awards that will take place live on February 8, 2009.

They join previously announced performers:  Kenny Chesney, Coldplay, Jennifer Hudson, Jonas Brothers, Lil Wayne, Katy Perry, and Carrie Underwood.

For record of the year, I think it will be either Leona Lewis (Bleeding Love) or Coldplay (Via La Vida).
