MV-K Your most favorite Apink title track?

[spopo]

I think it has to be I'm So Sick, just because when it came out, it was so different from anything they'd put out before, and was such an incredible surprise when it came out.  It was so conceptually different, but still obviously their easy listening synth sound. 

But Dumhdurum has the benefit of being recent, and it is so catchy.  We'll see if it overtakes.
