Someday (I Will Understand)

Whilst on “maternity leave” during 2005 Britney released a special one-off single to promote the DVD of her reality TV show “Britney & Kevin: Chaotic” entitled “Someday (I Will Understand).” She wrote the song shortly before she found out she was pregnant earlier in the year and sent it to London to be produced by Guy Sigsworth, with additional help from Kate Havnevik. The single was commercially released in Europe and was sent to UK radio to promote the DVD.
