Will “Tired of Waiting” be another homerun for 2PM?

As you all may have noticed, 2PM is now officially promoting their follow up track "Tired of Waiting."

The beastly idols made a huge dent in 2009 with "Again & Again" and then "Heartbeat" from their first album. Both songs were huge hits, but will "Tired of Waiting" be another homerun?

JYP Entertainment stated:

"Promotions for 'Tired of Waiting' began on the 1st of January. They will be wrapping up their first album promotions with this song, so the performances will be special. However, since this is their follow up track, we don't plan to promote the song for too long."

2PM first performed the new track on the 29th at the SBS Gayo Daejun, however they officially announced that they would promote the track via KBS Music Bank on January 1st, 2010.

What do you like better, "Heartbeat" or "Tired of Waiting?"
