I had to reload all the audio files (and uninstall and reinstall the Drupal Audio module), so all the music is back and Flash-playable. However, all the notes are (at least temporarily) gone. I also seem to have uncovered a nasty bug as well, where when one bit of Audio metadata is edited from within Drupal, all of it gets strangely truncated and has to be hand-edited in the MySQL tables (which I had to do FOR EVERY SONG). I'm not too happy with that state of affairs.
A number of improvements have occured on the site in the last 24 hours:
Not to mention glacial23 uploading his album 33 1/3.
