What's so hard about copying the music that you know you're going to be wanting to listen to to whatever device that you're going to have with you and then just listening to it? Why does it have to be streamed? If you have everything on an NAS then just use Windows file share and go to that folder and drag it to your foobar 2000 on your computer. If you're out and about and you want access to all of this then set up…
UPDATE: Also, sir, this is an Arby's.
