R.K.M y Ken-Y have competition. Not only do Gerry "Lionize" Hernández and Rafael "Raphy" Ramirez look and sound like R.K.M y Ken-Y, they're currently involved in a bitter feud with the popular romantikeo duo.

Hernández and Ramirez, aka Erre XI, made their debut on last year's Los Benjamins: La Continuación, alongside heavy hitters like Don Omar, Randy and Arcángel. Their contribution to the star-studded compilation, Vete, is a thumping club track with whistling synths, accordion flourishes and seductive complaints of a spurned lover.

Earlier this year, Erre XI uploaded Lloraré, a piano ballad about heartbreak to their MySpace. A few months later, R.K.M. y Ken-Y dropped their single Te Amaré with a nearly identical chorus. In fact, it's the same song. Luny claims "Lloraré," which was written by Wise (Hector "El Father," RBD, R.K.M. y Ken-Y) belongs to Mas Flow Inc., the Luny Tunes-owned label to which Wise is signed. Pina Records contends R.K.M. y Ken-Y bought the song from Wise. Luny counters he will take legal action against Pina Records for intentionally sabotaging Erre XI: "Nobody releases a single three months before their album comes out, unless it's a new artist."

No matter the outcome, Erre XI's debut album, tentatively titled Urban Soul, is scheduled for a late 2008 release. It features production by Luny Tunes, Tainy, Noriega, Doble A & Nales and guest appearances by Pee Wee, Ivy Queen, Arcángel, La Sista and Randy. In his MySpace blog, Hernández says there's plenty of room for another romantikeo duo: "The cake is very big and there is enough for everyone."
