Well, I'm intrigued with trying to debug things, code, ice makers (a recent fix), mysteries of the universe, so if you're willing, I'd also be willing to try a couple of things.
OK, so you downloaded the file, you can see it in your downloads or desktop in Finder on your Mac. When you say, "it still doesn't play", how are you attempting to play it? Are you double clicking on the file like you would a PDF? And if that's the case, when you double-click that downloaded file, does an app open up?
For example, if I make a totally fabricated file format, and double click it, I get this message in Finder:
View attachment 889007
On other words, the Mac doesn't know what app is used to open/view/play/eat that file. I don't have an app installed that handles that (totally bogus) file format (the format being determined based on the extension, i.e., the characters after the . )
You can also right-lick on a file and choose from a list of all the apps that can open the file, in this case, it's just a single default app:

OK, so far?
Now if I right-click ont he downloaded FLAC file, I get about 20 apps that chime in with "I can open that type of file", here's an abbreviated screen shot:

Any of those apps I could select and it would play correctly - also note, the top 'default' app, VLC, is the one that will open it if I simply double-click:

(and it's playing in my new Beyerdynamics that I haven't posted about yet
😀)
Maybe that will help.
I mean, alternately, I can just convert it to MP3 where it will play in itunes
😀
