personally to me it seems like it's a good way to judge GG popularity in korea especially when you watch the chart for multiple weeks
You obviously see a lot of GG going up and down based on if they had a comeback recently or not
But if you look the chart for multiple weeks you'll notice that there's 4 GG who seems to never quit the top 10 of the chart even if they aren't active or didn't have a comeback recently
and when you watch the performance of these 4 groups in the chart, it's 4 group who always get a top 10 hits lately
+ before mention it yes there's 2 other names who also always appear in the top 10, Oh my girl + Twice who fit in the fact that the tp 10 melon chart represent popular gg because both groups are popular for their past hits, but i didn't list them because they didn't get a top 10 hit recently
November (IVE isn't here because they didn't debut at the time)

Do you think it's a good measurement to know which GG are the most successfull in charts ?
