ZE:A garnered new fans, more popularity and newfound respect from people through their latest song All Day. With that in mind, they decided to release a better version of the song as their follow-up track. Even though All Day is a lively song for the most part, this one is even more upbeat. I kind of like it better than the original just because this one is more likely to be heard at a club, implying that it is a legit dance song. This is included in the repackaged version of their single album as the only additional track. Oddly enough, the song is titled R2+ All Day. I'm assuming that it stands for Remix 2 +. Regardless of the title, the track itself�is pretty catchy. Check it out: http://www.youtube.com/watch?v=tVOdNP9mpuQ
