Miss A releases "Good Bye Baby" teaser

Through a teaser website that was promoted by all of Miss A and JYPE itself, a teaser for Miss A's upcoming song "Good Bye Baby" has been released.  The website is very simple as it only has the month of release of "Bad Girl Good Girl" and "Good Bye Baby"; July.  Miss A's signature "A" legs are in the background.

The teaser is very short, about 20 seconds in length; but a lot is said in these 20 seconds...

The song "Good Bye Baby" has a vague feeling similar to "Bad Girl Good Girl" but seems to have a more hip hop feel (at end) mixed with castanets and electric guitar (in the beginning).

Now that we've basically deciphered this teaser to even smaller bits, watch the full teaser here.
Note: The teaser may take a few refreshes to play smoothly; the first few times may be a little choppy.
