If I could punch iTunes Match in the face, I would. Here's how I expect it to work. I add a song to a playlist in iTunes. Then I open iTunes on my iPhone or iPad, and see the same song in the same playlist. This morning I add a song to a playlist in iTunes on my Mac. I get to the gym and open iTunes on my phone. First problem: there are two copies of that playlist on my iPhone. Second problem: the song I added to it in iTunes on my Mac is not in EITHER of the playlists on my phone. This isn't an isolated event. Happens all the time. And yes, I did select the songs in iTunes on my Mac, right-click and "Add to iCloud" (though I don't know why I should have to do that at all). Has anyone been able to figure this out?
