This paper aims to rethink what our identity is in this global situation based on media theory. Media always created our lives and feelings like who we are. In the moment of globalization, it’s hard to understand what the core of cultural identity, because identity is always and already intrinsically mobile. The thesis tries to discuss the difficulty through one aspect of music culture. Music seems to clarify the practices for producing identities in globalization much easier in that music beyond various differences. The globalization fundamentally transforms the relationship between the places we are living in and identities. That does not mean we all live in the global spaces and construct our cultural identities in the global places. We all live in the local spaces which can extend their scale to the global spaces. Finally, this paper discuss the global network. Network can be connected global spaces with local spaces. Indeed we can reach the global network through media, yet we again reproduce our experience or identities at the local places.
