This chapter explores the interplay between piety and popular culture among young Muslims in Southeast Asia, focusing on the understudied role of hip-hop music. It argues that rather than a loss of piety, there is a transference of piety to secularSecular objects, challenging the notion that modernity leads to decreased religiosity. The article examines how Muslim youth are active participants in reinterpreting Islam, leading to its integration with popular culture. This phenomenon is characterised by the deregulation and de-dogmatization of religion, where traditional religious institutions and hierarchies lose their monopoly. The rise of a new media Islam further complicates the relationship between the state, transnational youth culture, and inter-ethnic competition. Despite controversies and state attempts at management, hip-hop, often fused with local elements and religious practices, thrives in the region. The article concludes by highlighting the dynamic nature of religious expression among Southeast Asian Muslim youth and emphasising the need for a more nuanced understanding of their cultural identities.
