Manage artist is a very good tool. But manage composer would be very usefull fo those, who collect mostly classical music.
Another problems:
1. There is no Chorus in statistic tool
2. There is no Chorus Master at all
3. Please introduce sort order for conductors!!! & Conductor profile
By the way I'had spent a lot of time before i bought OCD examining all CD collecting staff and OCD is the best!!!
