Xbox music help

So I recently worked on my music library on my Windows 8 desktop; adding music from iTunes and downloading protected files from the store. After my hard work, my library is at about 1000 song. Usually windows 8 does a good job syncing songs, but after I got my surface and set it up today, only about 750 of my song synced wirelessly (which is still impressive). I'm wondering if there is a way to get those 250 lost songs on my surface and if anyone else had any problems with their library syncing across their devices.
