Songs won't add to playlists

I think I figured out what's happening. If I'm on the playlists screen in iOS and I swipe to the left to go to My Music instead there is an option to 'show all music' - if I tap that then all the playlist attempts I have made show up. Unfortunately, I'm also seeing all of my wife's stuff as well ... the saga continues.

Yeah this approach didn't work for me. Added the songs to "My Library" and then to the playlist. Nothing showed up in either place. Got the little check mark confirming that it had been added and yet still my queue is blank. This is a major issue and really makes the whole Apple Music thing pointless. Looks like I'm going back to Spotify.

It's a default behavior of any Apple's cloud service. The same things I got in photos and iCloud Drive. Shame on you Apple. Go and hire someone who can make you cloud services the right way. Or buy Spotify or something.

Same issue here... I have added the same songs to a playlist multiple times, only to find they don't actually add. Very frustrating. Beats worked much better, so far.

Under "My Music", Click on the "Artist" or "Album" text and a menu will expand. Make sure the "Show Music Available Offline" is unchecked, and all of your stuff will show up. This was defaulted to Green, and is also the reason Beats Playlist imports won't show up initially.

Same here, except I would say this happens to me 100% of the time, not 80%. I have not successfully added a song to a playlist yet...

I am experiencing similar issues while trying to add existing songs (that I have downloaded to my computer prior to Apple Music) to a playlist. Whenever I try to add certain songs (sometimes this happens, sometimes it doesn't) to a playlist in iTunes on my PC, an iCloud icon with a line through it appears next to the playlist name. (To get to the place I'm at, click on the Music note in the top left corner, then click on Playlists on the top bar) Once I add this "broken" song to my playlist and the cloud icon with a line appears, the playlist automatically disappears from my iPhone without syncing it to iTunes.

I found that too--would create playlist on Ipad and it wouldn't show up on Iphone, Found this answer and it worked for me--go to settings on both devices, Music and be sure that Icloud Music Library is ON. I did not have that ON on the Iphone and as soon as I changed it, my new playlists loaded.

Think I found the solution.

I too set up my Apple Music account and went crazy adding songs to existing playlist and updating them all to include this new free music. I did this on my MacBooPro and then did a sync with my iPhone. On my iPhone, none of the playlists were there. NONE!

• So I flipped out for a bit then toggled off all the Apple Music switches on my iOS device for Apple Music, did a second sync, and they all came back... minus the apple music. This was a problem.
• So once again In iTunes I toggled the switch for iCloud Music Library off and then back on as you see below.

Apparently what this does is upload all the viable playlists up to their iCloud server then back down to your device. So this will take some time it could take hours depending on how many playlists, how much bandwidth, and how many songs you have. Once it's complete your music is up in the cloud and will sync to your devices... but if you toggled things off and on like me somewhere in the mix you might have missing songs (like all the apple music). (FIX below "SOME THINGS STILL MISSING?")

What's a Viable Playlist? A playlist can not contain the following

1. Duplicate Songs (if you changed the name or title of a purchased track you have created a duplicate in your iCloud library as it will automatically have all your purchased music). Not sure what the fix is for this yet I've yet to experiment.
2. Different Media Like Videos if you like me own the 4 minutes video by Madonna but didn't buy the song... well you're fine cause it's an apple purchase and it's in the cloud. However if you like me own some rando copy of Prince's Alphabet street that was given to you by a hommie a few years back well that will invalidate your ENTIRE PLAYLIST. See below how I did that very thing and the Faster dALE playlist is now killed it was removed from my iOS device as well. Removing the video fixed this... but then the playlist was kinda broken. (FIX in next section).

Some Things STILL MISSING? If like me and you did the step above, you will be missing songs on your iOS playlist vs the iTunes one... try these.

1. On your IOS device and in the iTunes windowToggle the make available offline switch on that playlist.
2. Move a song around in the playlist thats missing tracks (or not synced). It will then re-sync the playlist across the iCloud. All my songs that I had added in the iTunes playlist that were not on the iOS device immediately started showing up. It kinda threw the whole playlist out of whack (I think) for a second so moving things to where I wanted them on iTunes playlist fixed that, and was now mirrored on the iOS device.

Please let me know if this doesn't work for you or if it does. I would rather not be giving bad info to family and friends when they convert over.

I appreciate all of the work you put into your post but I think it should be it's own topic for discussion as it is unrelated to the OP's issue.

I am having the same problem with my iPhone 6+, I add music and it doesn't show up in the playlist , sometimes my playlist will show up if I add a radio playlist but the list of songs are empty. The interesting thing is my iPad does not have this problem. it could be a bug limited to certain devices. I know it was working yesterday at some point and now it stopped .
