The Motion Picture Association of America's film-rating system is used in the U.S. and its territories to rate a film's thematic and content suitability for certain audiences. The MPAA rating scheme applies only to films submitted for rating. The MPAA rating system is a voluntary scheme not enforced by law; and films can be exhibited without a rating, though many theaters refuse to exhibit non-rated or X-rated films. Non-members of MPAA may also submit films for rating. Other media (such as television programs and video games) may be rated by other entities. The MPAA rating system is one of various motion picture rating systems used to help parents decide what movies are appropriate for their children.

In the United States, the MPAA rating scheme is the most-recognized guide for parents regarding the content of films and each rating has been trademarked by MPAA so that they cannot be used by other organizations. The MPAA system has been criticized for the secrecy of its decisions as well as for perceived inconsistencies.

Kevin Johansen (born 1964 in Fairbanks, Alaska, USA) is an Argentine-American rock musician. Born to an Argentine mother, Marta Calvet, and an American father, he lived most of his childhood in the San Francisco Bay Area, but moved with his family to Buenos Aires at the age of 12. Later he moved to Montevideo, Uruguay, where he learned to play guitar.

Johansen made a brief appearance in the local rock scene with the band Instrucción Cívica with Julian Benjamin in the 80s who released two albums Obediencia Debida in 1985 and Instrucción Cívica in 1986, but went to New York in 1990. There he met and married his Argentine wife, with whom he has a daughter. He played in the CBGB's club for long years, until he created the group The Nada, and in 2000 recorded the album with the same name, a mix of different Latin sounds with modern pop, funk and rock.

During the same year, and with the new album in his hands, he returned to Argentina, where he currently lives. The album, released by Los Años Luz, was relatively successful and Johansen and the group went on tour as far as Spain (album edited there by K Industrias).
