You can say it was in their Prime YOU CAN .. they haven’t released bad title track since. All of them are all good. You can say not today was the last good One .. but that’s you that’s not everyone else’s opinion and a lot of people fell in love with the title tracks you don’t like. Bts aren’t like other kpop groups they don’t stay in a Category for YEARS or their whole life time as a group. They have done 3 English songs THATS ALL 3 I don’t think they sound like Bruno mars that’s your opinion. You don’t like their new songs but that’s a YOU problem. Not Bts as I said Bts don’t stay in one category of music. And if you don’t like that, that’s not Bts fault you don’t like some of their songs.
