xbox Muisc app and second drive

I know there are similar topics to this but I cannot find one that matches or a viable resolution. If I have overlooked one, my apologies in advance.

I've just moved onto W8 and and am now aranging things; folders etc. I have the OS on a 120GB SSD, and everything else on an internal 500GB HDD. I have added my videos folder on the HDD to the same livrary as the default videos folder (on C:. the SSD), and they show up perfectly in the desktop xbox Video app. However, when doing the same for music I cannot get the xbox Music app to see the files. If I move a song over to the music folder on C:, then it shows up right away. I have no other problems seeing the 500GB HDDl it's just the xbox Music app that will not see the music therein.

I have no idea why videos would show up in the desktop app just fine, but the music files fail to. I have added the HDD to the indexing list just to be sure, but it has made no difference.

Here's a screen shot of the music on the HDD added to the Music Library (just like I did with videos), but is still absent from the xbox Music app. As you can see I tried aking it the default folder as well, on the off chance it had some effect. It did not.

Am I missing siomething terribly obvious or is this just a problem with xbox music?

PS Moving my music onto my SSD is not a viable option due to size contraints.

Im not having any problem with Xbox music locating my music regardless of directory or drive, except external or network (for these certain sharing parameters must be met and/or installed).

However my win8 installation was in April 2013.. Xbox music had an update March 21, 2013, maybe i have the update, and you should get the update..
