[4] The EP consists of five tracks, of which is filled with Taeyeon's unique "#GirlsSpkOut" message, emphasizing that while there may be conflicts and sadness in everyday life, the essence lies in holding hands and facing tomorrow together.

[5] The title track "#GirlsSpkOut" marks Taeyeon's first venture into a dance tune, produced based on her message of expressing one's thoughts and showing one's true self, believing it will inevitably bring positive influences to one's life.

The EP also included "Be Real", a number that epitomizes the current global era with its fusion of R&B and Latin elements.

Furthermore, "I Do" is a mid-tempo and mellow tune imbued with Asian flavors, which interestingly serves as a message song from Taeyeon to her Japanese fans, fitting well with the autumn atmosphere.

Finally, the EP concludes with "Sorrow", a grandiose piece delivered solely through Taeyeon's vocals and piano, showcasing her utmost charm.
