This year's new twist in the Grammy nominations announcements is to roll them out little by little, tweet by tweet, as today goes by for maximum social media trendability.

The first of the major nominations to be announced this morning by Ed Sheeran and Pharrell on CBS This Morning was Record of the Year. (The other big categories are Song of the Year, Best New Artist and Album of the Year,the  last of which  will be announced on A Very Grammy Christmas Special tonight on CBS.)

And the nominees for Record of the Year are:  Iggy Azalea and Charli XCX, "Fancy"; Sia, "Chandelier"; Taylor Swift, "Shake It Off"; Meghan Trainor, "All About That Bass" and Sam Smith "Stay With Me."

The Grammy Awards will be broadcast on CBS from the Staples Center in Los Angeles on Feb 8.
