Describe what you expected should happen and what did happen. Please link any large code pastes as a Github Gist

Steps for reproducing this issue:

1. Scan Music Library (Local, NFS, or CIFS mounted share)
2. Status sits at "Building the Music Library" for each folder type for hours at a time with no music library being added,
3. Does not matter if a single folder or 10,000's folders are present, the music library doesn't build regardless. Have tried removing FLAC files and scanning with mp3's only, but still receiving the same result.
