To me many similarities exist between Molam and Cumbia: it is a music of the underclass, embedded in rural folk traditions stretching back decades and centuries; it has a mid tempo swing and a sensuous groove you can easily clap and move to; if reversioned for modern club sensibilities it would work wonders on the dance floor.
Yet is unlikely that Molam will enjoy a revival and become as popular with a western audience as happened with Cumbia in recent years, because South East Asian music have not historically circulated as much as Latin American music (of course due to no doubt a slew of political/economic reasons and not creative merit of the music itself).
