A DJ said he had a focus on songs from Southeast Asia and Japan

Yesterday, I caught a set by the DJ Itch , at Kult Kafé , Singapore. I heard songs with lyrics that sounded like they were in the language Mandarin Chinese, those with Japanese-like lyrics, and (at least) one that Itch said was from Indonesia, when I asked him where that song was from.

Maybe he - and the other DJs who spun - was playing vinyls yesterday.
