This is difficult, since I do like a lot of different eras and songs. One that stands out for me is 2 Cool 4 Skool/Bulletproof/No More Dream.
This is my go to album when I'm in a bad mood. My family knows if it is on then just to leave me alone for a while...or until the music changes.
Look how young they look....and they are all so adorable here.
Ah, they've grown up so much in the last 4 years.....
I know this era is an odd pick for me, but this is how I always think of BTS.
