Subway Restaurants has partnered with Univision Radio to sponsor the radio network’s 2010 concert series, with a twist. Subway will sponsor an opening act performance at each of Univision’s three major shows, slated to take place in the second, third and fourth quarters of the year.

The first show will take place in May in New York. The artists have yet to be confirmed.

The Subway deal also includes the launch of a site called “Subway Artistas Frescos” (Subway Fresh Face Artists) where fans are asked to upload videos of their rendition of the Subway jingle, a hip-hop ditty that’s been featured in Subway’s Spanish-language television ads since 2008. Those who visit the site today will already find fan videos that cover the jingle in different genres (there’s even a jingle featuring Univision Radio executive VP Jack Hobbs).

Video submissions will be judged on “uniqueness, creativity, originality and use of the jingle,” according to a Univision release. The top ten videos will be selected and posted on the site for visitors to vote for a winner that will be flown to each show. Submissions for the first contest closed March 21, and semi-finalists will be posted by March 29, with the winner going to the May concert in New York. The second contest will launch April 12.
