amazon mp3 sales, something has changed

Has Amazon removed their 30 second music clips, so you can no longer listen to song clips before buying them? Can you no longer buy individual MP3 songs?

I no longer see a play icon nor an add-to-cart option by each song.

There's a "Listen Now" button at the top-right of the page. If I click that button, it opens an Amazon Music page, and if I try to click the icon to play one of the songs there, it gives a message "On-demand listening is only available with Amazon Music Unlimited. Now starting a station based on your selection". Then it plays something else than the song I wanted to preview.

So, what does this mean? Amazon doesn't want to sell music anymore? They only want to sell streaming services? Or am I not being observant enough and somehow overlooking a new way to preview clips?

..

Now I've found 7digital.com, which appears to work the way Amazon used to. Though I haven't tried purchasing anything from there yet. So if Amazon doesn't work anymore, I may have an alternative. I wonder how they both compare in what they pay artists for each sale. I use Bandcamp when possible as I heard it pays better than Amazon, but it doesn't include as much as Amazon.

on comet

Yesterday I think I saw the comet, though I'm still not certain. Using binoculars, I repeatedly saw a faint blob, which I recall from somewhere is how comets often look, in the general area of where the comet should be. It was round, with no visible tail. Fainter but larger than the nearby pinpoint stars I could see.

I also saw another meteor right by the big dipper! That was spectacular but short-lived

Today I looked for the fuzzy blob again, but this time couldn't find it at all. The moon is bigger and brighter in the sky tonight; that might be why.
