In an unprecedented move, the GRAMMYs will continue to roll out the remaining categories and their contenders throughout the day via Twitter videos by various artists and celebrities.

Here’s what we know so far: Offering a mixed bag of fresh faces and GRAMMY veterans, some of the hottest names on the Billboard charts have landed a spot on the 2015 nominations list.
