Hot boy group 2PM performed their usual hit song "Again & Again" yesterday on MBC Music Core, but this time, they added a snazzy little dance intro before their actual performance. The boys were all on top of their game today, as their vocals sounded awesome. I don't know what it is about them, but these boys sure know how to get the crowd going. Thanks to Symbelmyns for the awesome HQ video! The dance intro that they did on Music Core, maybe it's the outfits, reminds me of the dance battle they had with SHINee earlier in the year. On a side note, check out some hot photos from 2PM's energy song, which will be out tomorrow afternoon. Nichkhun's plaid pants remind me of 2PM's old "10 out of 10" days... Good times... good times.
