I mean, I might be wrong, but—in the literal one? As in it preaches conformity and finding your purpose in following the group whatever the group is doing?

A glance at the lyrics makes me think my memory might have made this stronger than it actually is, but when I watched the movie about five years ago I remember thinking those lyrics were the first sign something was supposed to be off, and indeed I seem to remember that when the protagonist broke away from the prescribed routine he looked on with longing at the others “working in harmony” while the song is playing in the background.

It might have been cheery Soviet plays from the 1930s making me paranoid, but that song was the strongest impression the film left on me.
