Preview song on Music version 1.0

I'm thinking about buying some songs from the iTunes Store. When I fire up the Music program (Version 1.0.2.37), click the the "iTunes Store" button and start searching. I see a song I'm interested in and click the number to the left of the title expecting to hear a 30 second preview.

The first time I'm told I have to log onto Apple Music to play on my Apple TV. O.K. that is a bit weird as I don't have and Apple Music account, but I go ahead and enter my Apple password, nothing starts to play. After this when I click on the number l I get a message that says:

Apple TV can’t play this item. Have Yourself a Merry Little Christmas isn’t in Apple Music.

Why do I care if this is not in Apple Music? I don't want to listen to it in Apple Music. I just to sample to see if I want to buy in iTunes.

Any ideas? Is there a different program I should be using to browse/buy from iTunes?

Computer: iMac (Retina 5K, 27-inch, Late 2015) / macOS: Catalina Version 10.5.2

Thanks in advance and have a great holiday!
