Alert when file scan is complete

Hello,

   As the subject suggests, I'm wondering if EMMS provides a way to be
alerted when the directory scan is complete. Having some 4,000 FLAC
files, it takes about 30 seconds to scan through all of my
directories. In this time, my emms-browser (browse by: genre) window
only displays 'misc'. I have to manually press 'b 3' or M-x
emms-browse-by-genre. I've searched through the hooks and I don't see
anything relevant. Is there some other way to accomplish what I'm
after?

Regards,
Leander
