The gif says it all. My fave song ever by 2ne1 is Lonely. The first song that I listened to by 2ne1 is I am the best but the first one I actually tried singing along to was Lonely. I love all the versions of this song. The original version, acoustic one with and without Sungha Jung, the reggae one.. Just all the versions coz they all sound great singing it and yeah. I think this is the song that really showed their vocal abilities esp. Minzy and CL; Dara not so much lines in this song and Bom as usual nailed it.

I have not checked their Japanese version of this song yet. Going off to do that now.
