Using the subsonic mobile app you can designate where it stores the files it is streaming. If you set that cache to be very large ( in my case 20 GB ), then set the app to pre-download a large number of songs on play, and then also set it to only download on wifi it is pretty easy to pre-load with music and play from your device sans streaming. Hope that helps.
