哪首歌

In Chinese, this translates directly to 'Which Song'. This netname may suggest the person is likely musically inclined and enjoys music very much. Music might serve an important role in their lives, and songs might provide companionship, background noise during solitude, or means of expression that are hard to put into words otherwise. So naming after song hints that he/she wants others to ask which piece of music plays the most meaningful role or brings out some special memories in his/her heart and thus initiate potential social interactions centered around discussions of favorite melodies.
