40 free BtoB trivia questions with answers — music quiz, new questions added Oct 2026.
BtoB debuted in 2012 as a hip-hop-leaning boy band and then did something few idol groups manage: they changed lanes. A run of ballads in the middle of the decade turned them into one of K-pop's most respected vocal groups, while the members built parallel lives as actors, producers, radio hosts and musical-theatre leads. This quiz follows the whole story. Expect questions on who the members are and where they came from, the singles and albums that marked each turning point, the sub-units, the solo records, the dramas and variety shows, and the years when military service thinned the line-up. The opening questions suit anyone who knows a few of the songs or has seen a member in a drama. Later ones are for long-time fans who can tell a pre-release track from a title track.
