I never really looked at the Melon Daily Chart Top 1000 in any depth until the past few weeks, and I was quite surprised about what songs are still charting (77 girl group songs, or only 7.7 percent). I was also surprised by what songs aren't charting, where certain songs are currently placed, how certain songs rank relative to other songs from the same time period, and a variety of other things. What is the general public of Korea listening to as far as old songs? \n\n\nHere are the girl groups ranked by number of songs charting in the Melon daily chart top 1000 (dated February 14th):\n\nBlackpink: 17\nTwice: 11\nG-Idle: 9\nIzone: 7\n\nMamamoo: 6\nOh My Girl: 6\n\nRed Velvet: 4\nG-Friend: 4\nItzy :4\n\nAespa: 2\nSNSD: 2\n\n2NE1: 1\nT-ara: 1\nMomoland: 1\nA Pink: 1\nStay C: 1\n\n(Hidden Content)\n\n\n\nHere are the songs and their placements separated by year: \nI placed the current highest charting song, the rest are in spoilers.\n(I may have missed a group or two, I searched every group I could think of that might possibly have a song in the top 1000. However, every group listed has all of their currently charting songs accounted for.)\n\n2007: SNSD - Into the New World (#846)\n2008: NO GIRL GROUP SONG CHARTING\n2009: 2NE1 - I Don't Care (#662) \n(Hidden Content)\n\n\n2010-2014: NO GIRL GROUP SONG CHARTING\n2015: G-Friend - Me Gustas Tu (#954)\n2016: Blackpink - Playing With Fire (#208)\n\n(Hidden Content)\n\n2017: Blackpink - As if It's Your Last (#189)\n\n(Hidden Content)\n\n\n2018: Blackpink - Forever Young (#177)\n\n(Hidden Content)\n\n\n2019: Red Velvet - Psycho (#119)\n\n(Hidden Content)\n\n\n2020: Blackpink - Lovesick Girls (#6)\n\n(Hidden Content)\n\n\n2021: G-Idle - Hwaa (#23)\n\n(Hidden Content)\n\n\n\n-------\nMy Brief Analysis\n-------\n2009 must have been a big year to still have 3 songs charting, since there were no songs at all from 2010-2014 still charting, and only one from 2015. Also interesting that 2016 was a lot bigger than 2017, and 2018 bigger than 2019. If that trend continues, 2021 will be a year with less big hits than 2020. \nIt seems, with the exception of Blackpink's huge songs, most huge songs\/national hits (Cheer Up, Bboom Bboom, TT, Red Flavor, Gee for example) don't always have the long-term staying power as almost as popular songs from the same era. Maybe they get overplayed and people get sick of them? Idk. For example, I Don't Care is almost always considerably ahead of Gee on the Melon Daily chart top 1000. Both songs from 2009, both big during their release period, but Gee had a more explosive opening. However, It seems the GP listens to I Don't Care more frequently years later. This is the same type of situation with Blackpink's 2016 songs, even Stay, all having consistently better showings on this chart than either Cheer up or TT from the same era (more surprisingly, Russian Roulette also does better most days). \nG-Idle does really strongly among the newer groups (3.5\/4th gen groups)\nSome of Oh My Girl's songs from 2018 and 2019 still charting, also to my surprise.\nBesides Heartshaker, all of Twice's 2017 releases are notably missing. I would have guessed Likey to still be charting at least.\n\nI was most surprised that T-ara's one entry isn't Roly Poly or Love Dovey, but an even older song from 2009 I had never heard of.
