Context paragraphs:
Diario de la Marina: Diario de la Marina was a newspaper published in Cuba, founded by Don Nicolas Rivero in 1832.  "Diario de la Marina" was Cuba’s longest-running newspaper and the one with the highest circulation.  Its roots went back to 1813 with "El Lucero de la Habana" (The Havana Star) and the "Noticioso Mercantil" (The Mercantile Seer) whose 1832 merger established "El Noticioso y Lucero de la Habana", which was renamed "Diario de la Marina" in 1844.  Though a conservative publication, its pages gave voice to a wide range of opinions, including those of avowed communists.  It gave a platform to essayist Jorge Mañach and many other distinguished Cuban intellectuals.

Tatiana de la tierra: tatiana de la tierra (1961-2012) was a Latina lesbian writer born in Colombia, and the creator of the first international Latina lesbian magazine "Esto no tiene nombre"; the magazine was distributed in various parts of the United States and to many Latin American countries - like de la tierra's homeland, Colombia.  Much of her writing was bilingual and bicultural - featuring both the English and Spanish language - and contained very sexual content.  Through her work, de la tierra gave voice to LGBTQ people of color, and inspired other writers to speak about sex and sexuality in a very honest and shameless manner.

The Princess and the Frog (soundtrack): The Princess and the Frog: Original Songs and Score is the soundtrack of the 2009 Disney animated film "The Princess and the Frog".  It was released by Walt Disney Records on November 23, 2009, just a day before the limited release of the film in New York City and Los Angeles.  It contains ten original songs and seven score pieces, all but one of which were composed, arranged and conducted by composer Randy Newman.  "Never Knew I Needed" was written and performed by Ne-Yo.  The song had an accompanying music video which featured rotation on Disney Channel.  The song was also sent to rhythmic radio on October 27, 2009.  The songs are performed by various artists most of which lend their voices to characters in the film.  The score features African-American-influenced styles including jazz, zydeco, blues and gospel.

Hamburger Schule: As the name indicates, the movement was initially carried by Hamburg based bands like Cpt.  Kirk &.  , Kolossale Jugend, Ostzonensuppenwürfelmachenkrebs, Die Erde, Blumfeld, Selig, Tocotronic, Die Sterne, Huah!  , and Die Goldenen Zitronen.  Their music didn't necessarily sound similar, but was characterised by lyrics in German language (not a given in Germany) that gave voice to social criticism and were based on post-modern theory.  Consequently, it was lauded by the leftist trade press (especially "Spex" magazine).  The artists themselves didn't initially perceive these similarities to be particularly important and denied the existence of a homogeneous movement.  However, social links and political cooperations suggest that it wasn't unreasonable to view it as that.  Furthermore, it could be surmised that the term "Hamburger Schule" is a pun on the so-called "Frankfurter Schule" ('Frankfurt School') which is a school of neo-Marxist social theory, social research, and philosophy, centered at the Institute for Social Research ("Institut für Sozialforschung") of the University of Frankfurt am Main in Germany.  However, it seems more likely to be simply a clever knock at the need for legitimacy, by referencing the way all art movements are titled in German (e.g. "Wiener Schule", "Berliner Schule", "Österreichische Schule", "New Yorker Schule", etc.).

Wietie: Wietie was first published in 1980 by Christopher van Wyk and Fhazel Johennesse.  The magazine provided a literary platform for the prevailing philosophy of Black Consciousness.
