Q: I can't unhide a song in iTunes?

I am having the same issue. Tell me, is the song on a compilation album (by Various Artists)?

Whoaaaaa! I wasn't paying attention but now that you mentioned it, I'm having the exact same problem and all of the songs I can't unhide belong to a compilation album! Have you got any solution yet? I think it's a problem from Apple's end but I haven't found a way to unhide the songs, only to download them...

I also have the same issue. I've tried unhiding on my Mac, my windows 7 computer at work  and my windows 10 laptop. Same issue same songs.

One more guys, Exactly the same problem!

also i found, that i lost some of albums from my library which i purchased before... and i got recipes on these albums on my mailbox...

I too am also having this same issue. Trying to unhide an entire compilation album (Marvel's Guardians Of The Galaxy Awesome Mix Vol. 1) and to no avail, unable to unhide it. I am hoping that an Apple support technician can chime in and assist on this matter overall.

I'm having the same issue: I can't unhide songs from compilation albums. Does anyone have a solution?

Hide and unhide purchases in the iTunes Store - Apple Support

I'm having the same issue: I can't unhide the Godskitchen Electric 2012 album. Does anyone have a solution?

Yep! same same here.

Got probably a couple hundred tracks that are parts of "Various Artist" albums and can't download them.

This includes compilation albums, soundtracks and live albums.

For some reason Madonna MDNA Deluxe edition has been changed to "various artists" as well, so I can't get that either.

Will log a case with Apple and update

Yep same problem here. unhide button does not work for anything related to a compilation.
I paid for these songs and I want them back!!

I am having the same problem. Shows as hidden and when I click the unhide button nothing happens.
