Shazam has released its prediction of the artists that will win key Grammy categories when the 56th Annual GRAMMY Awards is broadcast this Sunday.

Last year, Shazam was recognised by the industry for being a reliable barometer for predicting Grammy winners, by accurately predicting three out of the four leading categories.

This year, Shazam looked at activity around seven key categories - Record of the Year, Album of the Year, Song of the Year, Best New Artist, Best Dance/Electronica Album, Best Country Album and Best Rap Album.
