2NE1 - They're disbanded, but for me, they're the ultimate girl group. They broke so many standards of kpop and all the girls are incredibly talented and have been through a lot. Songs I recommend: Ugly, Come Back Home, Lonely
Girls Generation: As a full group they're currently inactive but they have plenty of songs to listen to. They are the queens of kpop for a reason, they are truly on another level. Songs I recommend: You Think, Lion Heart, Genie. BONUS: Some of the members have amazing solo songs like Punk Right Now - Hyoyeon, Heartbreak Hotel - Tiffany and Four Seasons - Taeyeon
Sistar: Okay, last disbanded group I promise haha. The queens of summer have so many fun songs to dance to that will cheer you up. Not to mention they have one of the best female vocalists ever, Hyorin. (Also check out Hyorin's solo stuff, it really is amazing) Songs I recommend: I Like That, Shake It, Touch My Body
Blackpink: I know it can be hard to stan a group with so little songs, but Blackpink are really sweet and talented girls. Most of the members have amazing stage presence. If you want to get to know their personalities better they have a show on YouTube called Blackpink House. Songs I recommend: Playing With Fire, Stay, Kill This Love
Momoland: I know there's a lot of controversy around them, but I recommend watching Jessica Viba's video on their past, and clearing up certain things and showing they really aren't as bad as people say. Besides that, they are so funny and have the best personalities. Like seriously, I want to be all of their friends lol. Songs I recommend: I'm So Hot, Bboom Bboom and Freeze
If you like these recomendations and want more let me know! There's plenty more where this comes from lol.
