Laboum's Hwi Hwi and April's Mayday were some of my favorite songs of '17 (altho Shooting Love remains my favorite recent Laboum song). BLACKPINK had a really strong year. I'm surprised no mention of Bboom Bboom, I can't get it out of my head.
Hwi Hwi was close to making my Top 20 for 2017.
2017 wasn't as strong as 2016 I felt for Blackpink because they only released one song; it's cool that it was featured in Justice League though. It looks as though Jennie will have to take a break from watching Netflix all day since YG is letting them out of the dungeon for a comeback in April or May.
As for Bboom Bboom it came out in 2018 so that's why it didn't make my 2017 list, but it'll probably make my 2018 list. I can't believe they're still promoting it (they were on today's Muisc Bank); it's been almost 3 months.
I have to say that the first quarter of 2018 has been insane in terms of quality releases from girl groups. I can only hope the rest of the year will be as good
