Lolli, lolli, lollipop, there's a lot of lollipop

Lollipop is spreading... 

Cause, who doesn't like a lollipop eehh? 

We start of with Big Bang and 2NE1's Lollopop (2009)

And then we proceed with Big Bang's own Lollipop pt. 2 (2010)

Also, f(x) and M.I.C (Chinese version) Lollipop (2010)

And moving on to f(x) ft. SHINee's Lollipop (2011) No MV *sadface*

So... Big Bang helped 2NE1 to debut, through the LG phone - lollipop commercial, in 2009. The commercial went so well with Big Bang and 2NE1, that the company wanted to try it out in China too. And then it was f(x)'s turn to "help" or promote the new Chinese band M.I.C, in the Chinese LG phone commercial.

Than after that Big Bang have continued with another LG commercial, lollipop pt.2. With different lyrics and sound. And f(x) did another Korean version with SHINee.

Which one do you like the most?
