i wouldn't say i listen to cutesy songs, rather i listen to korean pop the same way i'd listen to western pop. i don't usually watch mvs so the visual aspect of brighter kpop songs are usually lost on me.
For example selena gomez has cute songs i listen to like tell me something i don't know and love you like a love song, same with miley cyrus's hannah montana songs. But i also listen to their more recent songs as well.
another example i can give is twice, most of their cutesy songs are my least listened to among their singles. songs like what is love, signal, tt and likey that have very cutesy vocals i don't tend to listen to a lot. At the same time i love knock knock, heartshaker and dance the night away.
Babymonster have a lot of potential but so far i their raps have not been outstanding, batter up was better than sheesh in everyway. and when i compare them to young posse's raps, i'd much rather listen to XXL than sheesh
