The 2007 Grammy Awards: Your Complete Guide

Did you know that Justin "Dick in a Box" Timberlake is up for four awards this year? Or how 'bout the man behind the "DNA of blues," Ali Farka Toure, and his posthumous bid for Best Contemporary World Music Album? And then, of course, we can't do without a plug for our very own, Senior Editor David Fricke's shot at Best Album Notes.

From uber-obscure to superstar, it's all here -- our official 108-category-deep companion guide to the two-and-a-half hour TV spot you're all going to sit down and watch on February 11th. Because we know you're not itching to spend $2,500 on a ticket for the L.A. show. But more because we know how daunting 108 categories can be, even if you are the biggest music nerd of them all.

To make it simple, we've organized the 108 into 10 categories. Listen to every nominated song, watch every nominated video and browse complete artist pages for every nominated artist, with album reviews, the latest news and more. Enjoy -- and stay tuned for our full grammy coverage.
