LOS ANGELES -  

Everybody's thinkin' about Frank Ocean.

Ocean is a cause celebre and the man with the momentum as Sunday's Grammy Awards approach. One of six top nominees with six nominations apiece, the 25-year-old R&B singer turned cultural talking point will have the music world's attention.

It remains to be seen if it will be the "Thinkin Bout You" singer's night. Ocean is up for major awards best new artist, album of the year and record of the year when the show airs live on CBS at 8 p.m. EST from the Staples Center, sharing top-nominee billing with fun., Dan Auerbach of The Black Keys, Mumford & Sons, Jay-Z and Kanye West.

Limiting Ocean's chances for a clean sweep are his fellow top nominees. Most are riding waves of their own.
