iTunes says that I'm not signed into Apple Music

Same problem. Tracks in Applet Music albums gradually all turned grey and then only my paid-for and ripped music was available. Have spent many hours trying to fix but nothing works. With many people being affected you'd think Apple would have found a fix quickly. Hope so. Only happened on my iMac. IPhone and iPad still working ok so not daring to sign in or out of either.

I've solved the problem today finally. The solution was surprisingly simple – I downloaded a song which couldn't be played. From that moment the problem was gone.

I was having a similar issue - strangely I could access and use all the Apple Music I had already added to My Music and also downloaded, but it wasn't letting my add new things to my music or stream anything. It would wait a while and then suddenly pop up asking me to sign up for Apple Music.

I took the wise advice of the characters from The IT Crowd and turned it off and on again. Everything worked normally afterwards. Whether it will happen all over again? Who knows. Until this whole Apple Music thing is perfected, I think we'll all have to deal with a few more roadblocks. Conceptually its great; they'll get there. Just might have to wait it out.

Another thing I noticed is that I wasn't able to play any song that was made available offline without getting the 'Not signed in to Apple Music' message, even though songs that I hadn't made available offline were working fine. I selected all of the songs in my icloud library and right clicked on the selection and chose 'Remove Downloads'. It works, but it did mean re-downloading all the songs when I made them available offline again...

Opening the radio and playing a station took care of this issue for me. I guess it somehow triggers Apple Music to recognize that you're already signed in.

Same problem. Why am I paying for this service when it doesn't work properly?

Hi,

I had the same problem for days! Even was on Apple support chat for hours with supervisor after supervisor and still nothing!
Finally I found a solution!
As I like to keep my computer clean all my songs are played from the Cloud.
So I decided to download the affected songs to my pc and then delete them again so they go back into the cloud.
And Bam its all working again!!

Hope this helps all 🙂

This is a joke. Paid for service and I get this message almost every time I stop the music to take a phone call or leave my desk for 5 minutes . No clear way to sign back in - and there should be no need anyway. Yet another Apple bug. I'm definitely cancelling and going back to spotify

You can see from screen grabs that you can be signed in but not signed in at the same time - clearly a bug

As others have said, this is definitely a bug. All the workarounds here are only workarounds and don't last forever. Yes, playing a radio station or doing something else to make it recognize that you're logged in makes it temporarily work, but then it stops again later on. Very annoying.

I found that when I started listening to Apple Music on my iPhone, instantly iTunes on my Mac said that the music iTunes music currently playing has stopped and that I had to stop playing on the iPhone. I stopped the iPhone, hit the "play" button on the keyboard and got the standard error "The song “Troubled Man” cannot be played because you are not signed in to Apple Music.". However double clicking the file started music in itunes

So perhaps iPhone usage is the cause of the Mac iTunes Apple error?

This was very annoying - every time you paused playback for more than a few minutes you would get this warning and have to move to a never previously played track to re-establish the login credentials.

However the latest update (OS X 10.11.1, iTunes 12.3.1.23) seems to have fixed it. 🙂

Yep, back to Spotify. I forced myself to use iTunes Music for a week or so to see if I could get used to it and convert from Spotify. Spotify makes it so much easier to create playlists, etc that this 'bug' just made it even easier to switch back. iTunes Music lost my $9.99 a month.

I am having the same issue, only on my mac works ok on ipad and iphones!.

I have family sharing all will be going right back to spotify. APPLE SORT YOUR SH*T OUT FFS

Here it happens to almost every music I have available to listen offline. You just have to remove the transfer. The musics that you do this will be able to be listened again! If you want to hear then offline, you have to download again.
