This why you'll see ranks for songs go down quite a bit as months go because artist promos are over, trials are expiring/expired, & all that's left then are the main sub base for US ARMY. Which is small. If smaller countries are having a hard time getting ARMYs serious about AM, how much more successful do you think that campaign is for the US? At some point we gotta to admit that overall, as a fandom, we're doing a lot more talking about supporting other platforms than seriously moving to do it.
When I as an AM subscriber can consistently come up in BTS Top 1000 listeners in US without much effort (Stationhead & random PLs) that means our firepower on AM is low overall so I can only imagine other countries.
For the USA, we cannot fight local songs/charts hard without more streamers on the platform. For as much as other countries scream at US about AM charts, you're screaming at the people who are there everyday & consistently showing up, we cannot make miracles. More support is necessary for the results we want on AM...US & Globally.
