It reached #3 on the Billboard 200 Albums Chart in the first 24 hours and later reached #2 during the week. A week and a half later, it was at #1. It sold 35,000 copies in the first week and 142,000 copies in the first month.

Theme
Submarine is about feeling pressured, stressed, having anxiety, etc. (as if you were drowning), but slowly things get better and you feel good (as if you're going back up to the surface and getting air). Submarine was made to help others and themselves with their stress issues and help them heal and get better.
