Monster is still #1 melon? Lucky One and Heaven are holding up well too. Have they always been this strong digitally? I used to hear they were just okay but here they are pulling off a double title track and an album track slaying as if it were a title track.
They aren't strong digitally (except Growl era), it's just the fans that stream the song all day so when sales are weaker (20:00-05:00) the other songs drop and they rise back to the top.
