The reason for the batch no7 being so obvious is because there are numbers of classical pieces labeled in a similar manner. I was thinking of adding Brewed in D Minor or something silly like that.
e.g.
2. Brandenburg Concerto No. 1 In F: I. Allegro
3. Brandenburg Concerto No. 3 In G: I. Allegro
4. Brandenburg Concerto No. 5 In D: II. Affetuoso
5. Concerto For 2 Violins In D Minor: I. Vivace
6. Concerto For 2 Violins In D Minor: II. Adagio
7. Violin Concerto No. 1 In A Minor: I. Allegro
8. Violin Concerto No. 2 In E: I. Allegro
