Music Changgo is a bar in the basement between the Seongsu E-Mart main branch and Ttukdo Market, where customers drink bottled beer while listening to LP music. Requests are taken for songs from popular Korean music to house music, played through JBL 4344 speakers. The space is soundproofed, and customers can ask for the volume to be lowered when it is loud. Even with many LPs on hand, the actual selection is sometimes played through web streaming.
