As every music fan knows, making the perfect mixtape is no easy task. Jim and Greg have thought long and hard about the art of mix-making, and this week on the show, they'll play their compilations of the best songs of 2006.

Ho Ho Ho! It's the Sound Opinions annual Christmas Music Spectacular with the show's official Kris Kringle, Andy Cirzan. Mr. Cirzan is back with another collection of weird, wacky, and ever-so-merry holiday songs for your listening pleasure.

They've made their list. They've checked it twice. And this week on Sound Opinions listeners will find out who exactly has been nice. Jim and Greg have tallied up their favorite albums of 2006, so tune in to find out who made the cut.

This week Jim and Greg are joined by former Police guitarist, and now author, Andy Summers. They'll also review new albums by hip hop duo The Clipse and rap-metal band The Deftones.
