4minute's Jihyun drew attention for apologizing to her fans on Twitter.

On April 13th, Jihyun tweeted, "For the first broadcast today my throat condition wasn't very good, so I thought to myself to just try to do as I had practiced, but I ended up filming live without my in-ear earpiece, which resulted in me showing you an unstable image."

She continued, "It's embarrassing to say, since it's all excuses, but I can really do better! I will try my best. Please continue to have interest in us and cheer us on."

Jihyun was apologizing for her performance during 4minute's comeback stage on the April 12th broadcast of Mnet's 'M! Countdown'.

4minutes's title track off their new mini-album, "Volume Up", is gaining much interest for lyrics that describe not only the public's enthusiasm for girl groups, but also their prejudices against them in a frank manner in a style that is uniquely 4minute.
