they do have other songs ^^ Nobody is their third single. They debuted with the song IRONY (with Hyun A of 4minute before Yubin took her place). There is a thing called "Tell Me Craze" in korea because the nation was swept oleh their Tell Me dance (my favorit aswell). Then they came back with So Hot (really cinta their princess syndrome concept) and then Nobody. If anda will cari on the youtube anda can also see some of their good songs like Stupid (E babo), I wanna, Saying I cinta anda (composed oleh Ye Eun) etc.
