Yes, I have a lot of digital music. So much so that it kills the hard drive on my computer. Because of this, I have the music split up in different libraries. One for school, one for Christmas, one for Halloween, you get the idea. There's a way I use to import back into my main iTunes library from these other libraries so I can synch them to my iPod. Yes, this includes Because It's Christmas from Barry, but it also includes some other favorites.
Someone took another favorite of mine - from Mannheim Steamroller - and added some Christmas lights. Enjoy.
