Ponderings

So, being Christmas season and all, I've got the XM radio tuned to the Christmas stations. Same old stuff. I still like it and all, but it seems that no one is able to write any new
Christmas songs that are anywhere NEAR as good as the old traditional stuff. Why is that?

Another thought I have while driving to and from work: music has been around since...well, forever. Many of the Psalms are actually songs, right? I took music lessons, there's only 7 notes (A-G) plus sharps and flats, plus octaves, right? So, mathematically speaking, isn't there a fininte number of ways notes could be combined? Will we run out of new music someday?

Is that why no one writes good Christmas music anymore?
