My default directory is \\Htpc-server\Music\
Billy Joel\Greatest Hits etc is the sub and sub-sub.
Auto import didn't work. I tried manually auto import, doesn't work either.
I still have a directory called \\Htpc-server\Music\Billy Joel\The Complete Hits Collection 1973-1997- Limited Edition Disc 2\
I haven't manually non-auto imported it yet. A manual auto import gives this:

Mp3 is selected as an autoimport file type.
Previously, autoimport always worked but I have only dumped files in root dir or in 1 level sub dir.
