NASHVILLE, Tenn. (AP) — It's a brutal year to be in the Grammy nominations handicapping game.

Sure, there are a few safe bets. Mumford & Sons and Frank Ocean are expected to take a share of nominations when they're announced Wednesday night during the televised Grammy nominations concert in Nashville.

And popular songs by Gotye, fun., Taylor Swift and Carly Rae Jepsen may land those artists on the list as well, but with no watershed albums during the nominating period for the 2013 Grammys like Adele's "21" it's not clear who will turn out as this year's top nominee.

All questions will be answered when the show airs live on CBS at 10 p.m. EST from Nashville's Bridgestone Arena with co-hosts LL Cool J and Taylor Swift.
