Ever since iCloud Match, this is how I sync music to my iPhone: 1) keep Match switched off 2) sync via iTunes to a playlist which contains music that I want on my phone all the time 3) switch Match back on. 4) then, normally, I will get a warning that Match will replace the library on the phone. That has always worked OK, as all that happens is that the existing music remains, and all my other music is available via the cloud. For the last few weeks, however, some albums are showing duplicate songs, i.e. the one from the sync and the same song with the Cloud symbol next to it. What is weird is that it is only some albums and not all. I've tried logging in and out of my iTunes account, but doesn't help. Any ideas on this?
