"Esta Navidad," a song written and performed by pianist Arthur Hanlon and sung by Puerto Rican pop artist Janina, is the Christmas theme song for several local Univision TV stations.

A TV spot featuring both artists is airing in New York, Los Angeles, Miami, San Antonio and Philadelphia.

The song, co-written by Claudia Brant, is available for sale on iTunes. Hanlon's album "Piano Sin Fronteras," is due Feb. 24 on Universal Latino.
