This is a great Christmas CD and the Chipmunks did a great job! It has all the classical christmas songs that I enjoy listening during the holidays, including their classic hit - the Chipmunk Christmas song. However, the last track-the Chipmunk Song, i.e. an additional bonus track, does not really fit into the whole theme of the CD. The tune is kind of off key with the new add-ons and I was kind of disappointed. In comparison to the latest Chipmunk soundtrack of the 2007 movie however, they did a much better version of the Chipmunk song with a couple of remixes and they turned out to be very contemporary, upbeat; it truly shows the Chipmunks really have the groove and they continue to rock into the 21st century! Well, 24 songs out of 25 are good, so it is certainly worth it to get this CD.
