^^ You should REALLY give IU a try. She's still considered an idol despite being solo and writing/composing some of her songs. Her latest album is already one of my top favorite Kpop albums of all time~
And I know I always say this but SHINee's songs and concepts are usually not what other idols would do imo, but it still dance/idol music. Their latest song Sherlock is proof of that XD
You might also like Sunny Hill, they're a bit like IU since they're from the same company but they're more mature.
I'll just leave these here
