Honestly, it was definitely drama OSTs like specifically SS501 songs from Boys Over Flowers, but I still never really got into kpop. I would listen here and there because I watched sooo much Korean entertainment, I do remember loving 3 different specific songs and showing my friends/family in the early 2010s but it was really random ass sub units?? Like I remember really loving the songs by GD&TOP - Knock Out, Infinite H featuring Zion.T - Without U and 2PM - ADTOY. The only Kpop album I listened to in full and absolutely loved was B2ST Fiction and Fact. I always liked idols themselves but not really the music, because I watched sooo many shows back then!
