Music for Millions is a 1944 musical comedy film directed by Henry Koster and starring Margaret O'Brien, José Iturbi, Jimmy Durante, June Allyson, Marsha Hunt, Hugh Herbert, Harry Davenport, and Marie Wilson.

[4] "Mike", age 6, arrives in New York to stay with her pregnant older sister Barbara Ainsworth, who lives together with a group of young women, her co-players in a symphony orchestra.

As the orchestra prepares to go on a tour of army camps, a telegram is received informing them of the death of Barbara's soldier husband in the Pacific war theater.

The talented Iturbi variously conducts the group as well as effortlessly plays difficult piano pieces, while Durante sings comically and acts as a grandfather figure to Mike.

In a surprise ending, shortly before giving birth, Barbara receives a letter from her husband saying he is in good spirits and convalescing in a military hospital.
