Popular idol group 2NE1 has made their mark on the international community through their latest single, "Lonely".

After releasing their new song at midnight on May 12th, the girls swept through all the major music charts, taking over the number one spot by the morning of the 13th.

More than that, on the internationally used YouTube website, the music video for "Lonely" has already attracted over one million hits, placing the girls at first place in the music sector.

Produced by YG Entertainment's mastermind Teddy, the song displays a more mature style from the group rather than their usual spunky style. It is a song about breaking up with a loved one, but the song has been said to maintain a certain liveliness while still reflecting deep emotion.

One thing to note about the girls' latest release is that 2NE1 will not be promoting it through the usual round of music ranking TV shows. Instead, starting from May 20th, they'll be performing unique performances and different renditions of "Lonely" every Friday on YG Entertainment's internet broadcast "YG On Air".
