As ticket holders entered Staples Center for the broadcast portion of the Grammy Awards ceremony, they were handed two items: a 240-page program and a mysterious white plastic bracelet. Its purpose became clear at the beginning of the show as Taylor Swift stepped onstage to perform "Out of the Woods." All around the arena, the bracelets lit up and flashed multiple colors during the song, creating a starry field of lights in the dark arena. When the song ended and LL Cool J took over the show, the bracelets had served their purpose and were never used again. With no way to flip the bright lights back on, many fans abandoned the white plastic give-aways on the floor when leaving their seats three hours later.
