VA - Now That's What I Call Christmas 4

This is nice to see some good new Christmas tracks by Rihanna, Lady Gaga, and Maroon 5. But I don't understand why they repeat tracks that were on previous Nows. One particular track is repeated way too much. Little Saint Nick by the Beach Boys. It is on Now Christmas 1, 3, 4, and the Essential Now That's What I Call Christmas. The only one it is not on is Now Christmas 2. Seriously, I don't see that it needs to be repeated that much. It's still a excellent track, but it does not need to be on anymore Now Christmas records. Some of the other songs have been on previous Now Christmas records as well. But the new material still makes it good. One track I am disappointed that hasn't made a Now Christmas record yet is Snoopy's Christmas by the Royal Guardsmen.
