Before you settle in for music's big night, it probably helps a little to know what to expect from this year's Grammy Awards. Like many recent outings (eh, who are we kidding . . . like every single Grammys ever), the 56th Annual Grammy Awards on Jan. 26 isn't loaded with a ton of rock artists -- there isn't a single one among the nominees in the top two categories, Record of the Year and Album of the Year.
