It looks like ArMak has it right. I have had iTunes turned on in the My Cloud all along, the My Cloud shows as another source of music other than what is in iTunes program database.
I had been underwhelmed about this since getting the MC, because the only music on My Cloud has only been from my iTunes Media folder from iTunes. It’s all the same stuff. But, this message cause me to look again, because a month or two ago I added music to MC from other than the iTunes folder. I added a folder of my wife’s downloads from eMusic to the My Cloud. So, I checked now to see if I could find any of it in iTunes from the My Cloud. I could not.
Hmmm. What’s up?.
I went into the MC Settings, found Refresh the iTunes database, and when it finished, went back to iTunes program and all her music is now listed under the My Cloud source along with my music.
So, if new music (i.e. a new source folder) is added to MC, to see it in iTunes it needs to be refreshed on My Cloud or it can be set to some auto refresh time. So, the feature works, and works fine.
I still won’t use it though, because I never play music on PC using iTunes program; how “old fashioned” is that! I have plenty of other ways to play from the My Cloud, so don’t need to play it’s music in iTunes.
