Broken Hearted-Girl is a filler on IASF. World Wide Women is a filler on the B'Day Deluxe Edition.
Broken Hearted Girl is not filler. If Broken Hearted Girl is filler then so are the majority of songs on 4. Plus, it was even released as a single instead of songs like Radio or Scared of Lonely. It's not filler.
And I'm altogether not here for B'Day deluxe. Only the standard edition.
