Britney Spears - "Someday (I will understand)"

Britney Spears says that she wrote the tune, which refers to her imminent motherhood, two weeks before she realised that she was pregnant. Spears : "I wrote this song at my piano, at my house. I wrote it two weeks before I found out that I was pregnant, so it was really kind of weird, because the song's about having a baby... and it's something that I'd been dreaming about for a while. It's kind of like a prophecy".
