 Houston is sometimes compared to larger, older cities and pop-cultural centers, sometimes being referred to as the "New York' or 'L.A' of the South", and is actually the fourth largest city in the United States, in terms of population size.The term 'Hustle-Town' was heavily popularized by Houston rapper SPM, following the release of "'Hustle-Town"' in 1998, directly utilizing the term in the name of the song, which was followed with a large rise in the usage of the term in hip-hop music and culture in the Houston scene.The term is also often used by sports teams, corporations, slogans, or groups in Houston, such as the Houston Astros, with the phrase "'Welcome to Hustle Town"', which can be seen painted on the south side of Minute Maid Park.
