You know how sometimes when you're listening to new music while multitasking, and then you realize "wait, no, this song is amazing, it needs my full attention and I have to restart this song"? "Hanoi" did that for me in the first 4 seconds. Best song (imo) in an album that just will not leave my head. The sound is like Japanese girl group pop + beach party + a garage vibe (= buy it now)
