Most anything JE. Until they decide that manorexia isn't an attractive body type and JE-feathered hair is just silly (because, let's face it, their primary appeal certainly isn't their musical artistry). At least the Korean boybands have slamming bodies.
Most anything visual kei. JE in superficial "rock" form, complete with manorexia and silly hair. Again, it's not about musical artistry (they're a far cry from the pillows, Mr. Children, B'z), so get some slamming bodies and good hair.
I can't listen to Korean music in general. Cheap production values and lack of musical identity. It's just subpar J-pop/C-pop. Even BoA sounds better in Japanese.
I do like how Korean male artists are HOT and have great bodies. So much more than the Japanese. So I don't really care if the music is second-rate, so long as I get to see the eye candy
And Angela Aki is a GIFT to J-pop. If only there were more like her and and less like Yui, finding joy in music and performance rather than reticence and apathy. Stop being "cool", Yui. Same for you, Hikki.
