I think I can help you here. Things are just a little different but may prove better in the end. To start, the switch to
"Show all Music" and to show only "Download to device". is no longer located under Music in settings, it's now in
the music App making it much earlier. So, go to your Music App and use the upper drop down switch to change
from Artists view to Album view for example. If your there, scroll down to the very bottom and that "Show Music"
is there but it is now called "Music Availlable Offline". It's the same thing just different terminology as Apple begins
to reference off-line mode for their new music service. To us, it's the same switch only no longer in settings. As for
your music, just as you said, music that was in the cloud previously had a cloud icon next to it. That has been
replaced using a somewhat inverse method. Instead of telling you what's in the cloud, it tells you what's on your
device and those songs with nothing are assumed to be in the cloud. What's on your device will have a tiny bookmark
next to it. All those without a bookmark are downloaded to your device but accessible from the cloud. Try downloading
a song from your iCloud. The three dots you mentioned on the right is a menu with many options, one of which says
"Make available off-line". Same as downloading just new terminology. After the download, the bookmark appears next
to your song Indicating it's been saved to your device.
