How do I restore purchased Apple Music songs that were accidentally deleted?

Well, that got me started in the right direction, so thank you! My mistake and solution (for anyone experiencing the same problem) I kept going to iTunes Store where it showed that I had already purchased the song, but it still would not play more than a 30 second sample clip.

So I went to the Get Info, then to the File tab, which confirmed the song was in my Apple Music folder on my iMac. From there I went to the Sorting tab. There was a single "sort as" line that did not have the artist listed (all of the others did), so I filled that in, and saved it.

From there, instead of right-clicking on the album and going to "Show in iTunes Store" (which didn't help at all) I went to "Show in Apple Music". When the album came up THIS time there was an option to add it to the Library, which finally worked.

But I did unhide the song before I made this original post yesterday. Still unable to download. So I did the typical restart thing, then tried again. No change. I went back to the list of hidden items. While there are a few songs that I deleted in the hidden list, this song is no longer on the list.

Let me add the following information. I purchased the song from the iTunes Store a few years ago. I did NOT have a subscription to Apple Music at the time. Currently I have 3 free months of Apple Music due to a recent AirPod purchase. So under Apple Music I added the rest of this album to a playlist on my iMac. I did not purchase the rest of the album, so if I do not continue with the Apple Music selection, most of these songs will disappear, with the exception of the two I purchased a few years back.

But right now, with the subscription, here is what I see in the temporary playlist...

So on the line with the song "Sound and Vision", off to the right is the circle and arrow that shows up on all of my purchased songs, and hovering over it, it says "downloaded". Same thing with the "A New Career In A New Town" song that I purchased a long time back. All good so far, right?

Now, if I go over to where ONLY my purchased music is (not my subscription Apple Music), the song is no longer there when I go to this album. Only one of the two remain, whereas before this accidental deletion, there were both songs.

If I go over to the list view, same thing when I search by artist, or search by song title. The song is no longer there. So since the song is not hidden, where did it go?
