Soma fm is also one of the stations you can use on Sonos , go to add a service.

I listen to it every morning when I wake up.  Here's what I just listened to this morning:

We thoroughly enjoy SomaFM's Department Store Christmas as well, Will.

Others we use are 181.fm Christmas Standards ( http://player.181fm.com/?station=181-xstandards )  and Christmas Vinyl at walmradio.com.

The Internet Archive (archive.org) has some Kmart and S. S. Kresge in-store Christmas music, complete with "Attention Kmart shoppers" interludes - quite nostalgic for those of us who shopped places like Kmart and Two Guys with our parents.

And for those of you who like old radio airchecks like I do, a favorite is Max Kinkle on WCBS-FM on Christmas Day, 1983 (in four parts on YouTube).

KSFI FM-100 in Portland, OR from the 1980s is another one (also on YouTube), and there are many more.

Wow, this is fantastic!!  Thank you for the recommendation!

I randomly checked in on 'Department Store Christmas' earlier this week, and was happily surprised to see that they have already switched over to Christmas music.

I emailed the soma fm station manager a few weeks ago and asked when they started playing department store Christmas, I was told October 1st , enjoy!
