That is true, back then there were other artists rather than idol groups like BTS and B.A.P who wrote socially conscious music, but the difference between them was that these two groups were idol groups, they have the visual + dance routines packed with good lyrics and music which made them distinctive against other idol groups. Usually male idol groups sing about being “so cool” or love and heartbreaks, but these two groups chose a different path and take on music which is why so many people ended up liking them, and they didn’t just do it once or twice or here and there, they’ve done so multiple times. I believe when it comes to these two groups, looking at the lyrics is an important section since it’s a big part of their music, hence why we have professional translations or translators take their time so they convey their words perfectly and raw. If you go on twitter there are many good translators which do a great job and also there are some great analogies and the different perspectives on the songs. With these two groups it is a must. That depends on the person, I personally learn the meaning of the songs and play them depending on my mood. It’s very rare when I jam to a song where I don’t even know what they’re saying... but I see what you mean I would say this again, because both BTS and B.A.P have great lyrics, people usually anticipate what they’re preaching about next In their songs and that is something you can’t really do with many other groups in general. With other groups you’re free to groove with the beat whether you like the lyrics or not. These two groups have taken different routes and I know this might trigger some people, but In a few decades, if they still remain together I can see them being respected like Epik High. If Baepsae had lyrics about love then yes it’s true that people would still jam to it because that song is clearly iconic, but the hype will soon die down because it’s would just be another generic love song, but because people subconsciously know what the actual lyrics to Baepsae are and how important of a song it is to BTS, people still talk about it because it triggers discussions. I need you has lyrics about love and a good beat, but if it weren’t because of the storyline and theories behind it, it would’ve been soon forgotten as another love song like many of their old love songs (to name a few Just One Day, Autumn Leaves, For you, Blanket Kick etc..) because they’re the type of songs that you get over them after a while... So yes, I do believe their lyrics and take on social issues is something that rose them both to them top, and hopefully less people sleep on B.A.P, even though their popularity seems to be increasing steadily too, right now they really need a hit song like Dope or Fire. Not saying an exact song like that, but they need something memorable like those two songs which are in fact also about societal issues but are more “on your face” with things like “I’ve worked harder than you and now I’m successful” and the other one the almost typical “fuck what people think, live your life how you want”. You might say something about Blood Sweat and Tears since it was a successful song of BTS and that song is in fact really sexy but the reason they didn’t become one hit wonders is because again, it had connections with the storyline they’re creating and the hint in the lyrics and whatever... you know, all those theories. Otherwise this song would now be long dead as another “typical pop song”.
