do seventeen’s album sales make sense?

No. Not at all. Jungkook with 1 album close to 2.8M sales:

Spotify - less than 60M to 5B streams

Youtube - 2.1B audio streams

Apple Music - out charted 17 whole career with 6 songs (1 song alone outlasted all of 17 songs combined)

Total Audio Streams - 9.1B

Mind you this is all with just 1 album and 16 original songs.

Their sales make much more sense than NCT Dream selling 4M of their last album or even Treasure’s last album Gaon/Circle sales.

When you look at it that way then 17 are BTS level.

I'm reminded again how Jungkook was a beast with Seven again. No wonder he was scouted by 7 labels they knew the gem that is Jeon Jungkook.

OP, what do you mean exactly?

With how many members they have, I assume the bulk buying that goes into it just to buy their fave member poca
