iOS 9.2 Apple Music won't download my music to iPhone

I updated my iPhone 6 to the new iOS 9.2 and after updating it took all my music off my phone that I had downloaded, even the songs I bought off iTunes prior to Apple Music. I have a smart playlist that has every song from a specific date (I think it is from 6/1/15) that has been added to my music and when I find music I like i just download it and it downloads it to that playlist on all my devices. I use a Mac Air as my Main center for music. Now when I use the new "cloud" make available offline button on my iPhone to download my music in that playlist, which has roughly 950 songs, to download the music onto my phone it only downloads some of the songs and it puts the new dotted "downloading" circle next to the song and it doesn't move or do anything no matter what I do... Even if I try to cancel the download by tapping the "stop" button on that song it does nothing. It is like it is frozen on it or something... Then just to stop it all I tap where the new "cloud" make available offline button would be that is now the new "stop" button and when I tap that it exits out of the download of the songs but instead of keeping the song that have already been downloaded onto the iPhone it deletes every song in that playlist and makes it unavailable offline.... It is so frustrating... I don't know how to handle it. Apple is making this very freaking difficult to make your music available offline on our devices. I don't see why they can't just add a button that makes everything in your library available offline. The only thing I am probably going to end up doing is go through every song in my library which is like 2500 songs and individually making them available offline... Which I have done in the past and I have tried to do recently but again some songs just won't download... I don't know what to do. This is possibly a bug with this new update but I don't know. Any ideas??
