I think Duble Sidekick may suit KARA in Korean style, But for Japanese, Sweetune may more suitable.
Honestly, I'm prefer the Korean style (Step Album and Full Bloom),
However, for the Japanese Album, I hear a lot too, but *sorry*, I feel somewhat embarrased or guilty to play it when there's my friends or parents. Except for the "Ima, Okuritai Arigatou"-style songs...
Anyone feeling this?
Sorry if someone hurt when I write this
