Can I still preview songs before buying in iTunes Store?

On my iMac (OS Catalina), I open Music. Yes, I am signed in to my Apple account. The, I click [iTunes Store] in the left pane (under Store). New material appears in the main window. (For example, I can click Justin Bieber and preview his songs. They play fine. Hey, he just happens to be the first item shown.)

However, the only Search" box I see is in the left pane, at the very top. So, if I enter "Beatles" or "ABBA", I get results... but cannot listen to them. Instead, I am repeatedly hounded... er, invited to subscribe to Apple Music.

I click "Not Now" at the very top of the dialog to dismiss the invite. Then, I try again to preview a Beatles song - and am I thrust back into the subscribe cycle of death. What am I missing?
