Same here, but it seems that Firefox let’s you do more. Stop using IE on this one because the interface will not show completely.
Despite that, even using Firefox, the user feedback is poor. It does not tell you if entries are saved or not. I need to reload the page to reallise that I saved the same items several times without knowing it.
My worst issue is that, even after creating albums, songs and allocated a WP page for it, I still cannot see anything on my discovery page :-(. Maybe I just have a conflict with other plugins I have installed on my WP.
Currently looking into the plugin code to see what is going on.
But as expected, this plugin does not re-use existing WP tables, here they are:
# wp_discography_categories
# wp_discography_groups
# wp_discography_songs
# wp_discography_song_group
