Mãi Mãi Là Của Nhau (Mine) is an OST song for the movie 4 Năm, 2 Chàng, 1 Tình Yêu starring Harry Lu, Anh Tú, and Midu that was released this month. Produced by DoungK and sung by singer Bùi Anh Tuấn, Mãi Mãi Là Của Nhau is another well-put-together Vpop song that I would categorized as an EDM pop ballad song. It looks like Vietnamese EDM pop ballad songs are here to stay, and I'm totally fine with that. In fact, I couldn't be happier since I am one of those people trying to ride this EDM pop ballad hype train as far as it can go. All aboard the hype train!
