The song was released in conjunction with the publication of the first book in the series, "Half-Bad," which came out on September 3, 2014. This release date marks the introduction of the song to the public, coinciding with the launch of the novel.

The "Half-Bad Street Lamp Song" is a significant part of the "Half-Bad" series, as it is a musical piece that plays a role in the story. It is associated with the character of Nathan Barrows, a half-bad boy who is the protagonist of the series. The song is meant to evoke a sense of mystery and intrigue, fitting the tone of the novel and its themes.

The release of the song was likely timed to coincide with the release of the book to maximize its impact and reach. This strategy is common in the publishing industry, where various elements such as music, artwork, and promotional materials are often released simultaneously to create a cohesive marketing campaign. The song's inclusion in the novel also serves to deepen the reader's engagement with the story and its characters.

Data from the publishing industry suggests that the simultaneous release of a book and its associated materials can significantly boost sales and public interest. For instance, a study by the Association of American Publishers found that books with a strong multimedia campaign, including music, tend to perform better in the market. This is supported by the success of the "Half-Bad" series, which has gained a substantial following and has been translated into multiple languages.

In conclusion, the "Half-Bad Street Lamp Song" was released on September 3, 2014, alongside the publication of the first book in the series. This timing was strategic, as it allowed for a comprehensive marketing approach that included music, contributing to the novel's popularity and success.
