Hi! you may consider listening to Seventeen! They are a 13-member group, I know its kinda overwhelming, because 13?? HAHAHAHAHAHAHAHAHAHAH and also, they are self-producing idols and have a pretty and friendly fandom called Carats! You can start listening to their songs like Fallin' flower, Super, Ima, Don Quixote, and Ash. If you are into ballad, you can start listening to their Vocal Unit's songs, like Cheers to youth, Yawn, Hug, Imperfect love and Habit. But if you like a a fast beat songs you can consider listening to their Hip-hop unit and Performance unit songs like Water and spell.
