BTS's J-Hope is continuously dropping teasers for his upcoming solo album, "Jack in the Box." At midnight of Friday, July 8, the rapper dropped a teaser of his tracklist through an abstract 3D video.

J-Hope revealed the titles of the ten songs in his album, "Jack in the Box." As expected, this excites his fans and the BTS fandom per se, seeing the "interesting and exciting" song titles.

AllKpop noted the album would feature the songs "Intro," "Pandora's Box, "MORE," "Stop" and "= (Equal Sign)." It also includes "Music Box: Reflection," "What If...," "Safety Zone," "Future" and "Arson."

Meanwhile, the idol dropped the pre-release of his song "MORE" on July 1 and it instantly climbed to the top of iTunes song charts in 85 countries. The hitmaker also quickly earned the highest-charting debut by a Korean soloist in Spotify's Global Top Artists chart history.

Its music video, alternatively, now has more than 33 million views and sits No. 5 on the music trend. On Wednesday, July 6, J-Hope released a behind-the-scenes clip of his new solo music video and showed his fellow BTS member V's surprise cameo, per Soompi.

He first expressed his excitement as he prepared to film his scenes and described the concept behind the set. At the time, he revealed he had various sequences to do, and each would be shot in different rooms.

One of the reasons the video would feature several rooms was because the song was called "MORE," making him want to show "more different spaces" that held different meanings. He continued that they put a lot of work into creating and expressing each room, adding he put a lot of attention into bringing more energy and making each space more conceptual.

"If you look at the big picture, all of these rooms are formatted within a box," he said. All rooms were inside the box and fans would see its structure at the end of the music video.

On the second day of filming, V surprised J-Hope with his unexpected visit to the set and brought him waffles. The "MAMA" hitmaker was evidently happy seeing Kim Taehyung and introduced the latter to everyone as his bandmate.

V then offered to be part of the mannequin challenge scene in an unplanned cameo. This made J-Hope more excited, saying fans would surely notice his appearance right away.

Meanwhile, BigHit Music revealed all the tracks in J-Hope's solo album, "Jack in the Box," would be out on July 15, while the album itself would drop on July 29.
