Britney Is The Sole Writer Of Someday

It was confirmed on the back of the European "Someday" single scans that Britney is the sole writer of the song! Meaning she wrote the lyrics, (as we know) and the music aswell! This means that "Someday (I Will Understand)" is the first song Britney has ever written completely by herself. Britney wrote the lyrics and melody for "Everytime" but had help from someone else for the strings arrangement.
