I originally posted this in the Microsoft Community but was told that I might have more luck on here.
I have all my music on a 64 GB SD card that I keep in my new Lenovo Yoga. I have it mounted to my Music Library so that Zune recognizes and adds everything in my SD card to my Zune collection as if it were there on my SSD, freeing up 40+ GB and counting. This device only has 128 GB of SSD so this was necessary. Zune picks up and plays the music flawlessly.
Now, I want to be able to use Xbox Music to play my music because the pause/forward/back and info when you press Volume is very nice and I'd like to be able to use that, but Xbox Music isn't picking anything up from my Music Library the way Zune does. Zune works perfect with it, why can't Xbox Music?
