9/10 of songs on the current melon top 10 are from idol groups or idols (ditto, omg, antifragile, hypeboy, vibe, candy, love dive, after like) 
this was far from the case exactly a year ago when only 3 idol group songs occupied the top 10 (eleven, dreams come true, step back)
let's not even talk about 2019 when dalla dalla was pretty much the only gg smash hit song
what changed in the span of a year? are we just witnessing the start of 4th gen's complete takeover?
