Hi, I have mycloud connected or linked to my itunes library just fine. I am sure you can access the files and play them with whatever media player you may have at work or wherever.
I have all my music on my shared music folder in the mycloud and can play the songs from my phone, other computers, etc.
I have been able to link itunes to the media folder on the mycloud but havent tried to do it outside of our house network. (I am not the best apple user out there). We have also been able to connect to the mycloud music files via appletv and that works well.
Hope this helps.
