Algorithmic curation on platforms like Spotify and Joox amplified the song’s reach through “Discover Weekly” placements. By tagging the track with both “Indonesian Pop” and “J‑Pop” metadata, the label leveraged cross‑genre recommendation loops, a tactic supported by recent research on algorithmic genre‑blurring (Tan 2023).

This paper examines the 2023 Indonesian pop‑song Istriku Dientot Pria Lain performed by the Japanese‑Indonesian artist Michiru Kujo (stage name INDO‑18). By situating the track within the broader landscape of contemporary Indonesian popular music (Indo‑Pop) and the trans‑national flow of Asian pop culture, the study investigates how the song negotiates themes of marital infidelity, gendered power, and self‑assertion. Using a mixed‑methods approach—textual‑lyrical analysis, semi‑structured interviews with fans, and a digital‑ethnographic survey of social‑media discourse—the research reveals that the song functions simultaneously as a cathartic narrative for listeners, a subversive commentary on patriarchal norms, and a strategic product of the “Indonesian‑Japanese hybrid” market. Findings suggest that Istriku Dientot Pria Lain catalyzes a re‑articulation of female agency in the digital age while reflecting the commercial logic of the “INDO‑18” brand, a label that fuses nostalgia for early‑2000s J‑Pop aesthetics with modern Indonesian urban sensibilities.
