This is about 7 months after her previous release in Korea, ŌĆ£HappyŌĆØ. Combined with unique instrumental sounds, ŌĆ£What do I call youŌĆØ is a minimal yet rhythmical R&B Pop song. In particular, TaeyeonŌĆÖs vocals shine through the song as they portray a calmness that lingers around a break-up. Taeyeon introduced the song as ŌĆ£a mixture of coolness, indifference and a drop of hip-hop.ŌĆØ While Taeyeon usually gets more attached to songs in the album which are not the title track, that is not the case this time. She chose ŌĆ£What do I call youŌĆØ to be her favorite from the album and explained how ŌĆ£the melodies and feels of the songŌĆØ aligned well with her style. ┬Ā Source (1)
