As K-Pop group BAP prepares their first full-length studio album, they are slowly revealing details to their fans. Yesterday they confirmed the tracklist, today they have revealed which song will be used as the lead single - "1004' (Angel)" - and that it will drop on February 3.

After cluing his Instagram followers in on the upcoming album's progress, BAP leader Bang Yong Guk revealed a picture of what appeared to be a handwritten tracklist, thus piquing interest in the start of BAP's activities for the year.

Not long after, the group's agency, TS Entertainment, confirmed everything and added that the group's LP will be titled First Sensibility and is set to contain a total of thirteen tracks.

On January 16, the company further revealed that the second track on First Sensibility, "1004 (Angel)," will be used as the title track.

The image shared by TS Entertainment announcing the new single also confirmed that the song's premiere is only about two weeks away and is sue out on February 3.

"1004" is a clever play on words that translates to "angel." In Korean, the word for 1000, "chun," is added to the word for the number four, "sa," to make "chunsa," which means "angel."

The new promotional single is expected to be a love song that carries with it a concept quite a bit different from BAP's usual intense and somewhat aggressive hip-hop style.

According to the agency, the BAP members will explore a sexy, playful side of themselves as they transform into matured, sensitive men.

After a knock-out year in 2013 with several chart-topping singles, an official debut in Japan, and a US tour, fans around the world are definitely looking forward to what BAP has in store for the new album.

Stay tuned for more details regarding First Sensibility and BAP's highly anticipated comeback.
