Mumford & Sons’ Babel and Frank Ocean’s Channel Orange are the two albums that absolutely, positively can’t miss receiving Grammy nominations for Album of the Year. Babel, Mumford & Sons’ sophomore album, is one of the year’s best-sellers. It topped The Billboard 200 for three weeks in October. Channel Orange,Ocean’s freshman album, debuted and peaked at #2 in July.

Mumford & Sons’ 2010 debut album Sigh No More wasn’t nominated for Album of the Year, but a song from the album, “The Cave,” was a finalist for Record and Song of the Year last year.

The Grammy nominations will be announced on a live TV special on Dec. 5. LL Cool J and Taylor Swift are set to co-host the one-hour show. The awards will be presented on Feb. 10.
