In this paper we analyze, as an example of oral political discourse, the songs of two main Spanish politics parties, during the general 2008 elections. As other texts of political discourse (such as speech, interviews, meetings, posters, advertisings, etc.), these songs that accompanied the electoral propaganda are part of a public and ideological discourse aimed at the election of a candidate (perlocutive object). The elector voting for the candidate must believe that he is the best option available. Thus, the candidate's discourse is directed so the elector knows that the candidate and his party are the best options (legitimation), while it presents the opposing candidate as the worst one (delegitimation). The results of the analysis show that these strategies, quite typical in political discourse, have some new elements such as their resemblance to commercial advertising, i.e. the testimonials by famous people. Even if the political songs are a traditional genre with conventional communicative aims (propaganda and persuasion), they display some typical features in contemporary and postmodern communication: colloquiality, informality, "carnivalization", syncretism and hibridation.
