LOS ANGELES -- Nominees for the 56th Grammy Awards on Sunday will be up all night to get lucky, including "Get Lucky" performers Daft Punk. But who will take home the coveted gramophone trophies? While observers continue to predict who will win, two music services -- Spotify and Shazam -- are placing their bets based on their users' engagement.
Spotify based its predictions, below, on streaming data to see which artists, songs and albums its users listen to the most. Last year, Spotify accurately guessed the winners for Record of the Year ("Somebody That I Used to Know" by Gotye feat. Kimbra) and Album of the Year (Babel by Mumford and Sons).
Meanwhile, the folks music-identification service Shazam analyzed total activity for each nominee. In 2013, Shazam correctly predicted three out of the four top categories.
Here are Spotify and Shazam's predicted winners (the two companies looked at a few different categories), along with a list of contenders in each category.
