Before I get to the issue, the Pi2 + OSMC perform excellent together. Good job 
Whenever I try to play music through file view, not the library, OSMC freezes and does not respond to any input. Restarting the service via SSH is possible, so not the entire Pi is stuck.
Here is the interesting part: The problem seems isolated to playing files located directly one the SD card OSMC is running on. Part of my collection is in ‘/home/osmc/Music’. Playing from external media is working fine.
Short of moving my entire collection to the (slower) spinning drive, do you see anything that would cause this?
