"We could be kings of the world on top of the nation, it's a celebration of the moments to come... it's time to celebrate like New Year's Day." Here is a hit song from Pentatonix's 2015 self-titled release, perfect for programming at any time of the year. This fantastic arrangement calls for piano accompaniment with simple synthesizer, percussion and bass, or you could try it a cappella. Either way, it's sure to be a crowd favorite at your next concert.
