This issue still occurs on the latest Aries and Flame Master builds using NGA Music.  Note that this issue does NOT occur with OGA so it is NGA specific.

Actula Results: The music app does not refresh available audio files when unplugging the usb cord.

So the issue here is that we only get the enumerable event once. Later, we transition directly from unavailable to ready. Thus, we need to be sure that we unblock the functions that require an enumerable database when we transition to "ready".
