The Lane 2 on TWICE's TWICEcoaster release showcases the K-pop sweethearts in a refreshing new spotlight. Centered around lush production that recalls Katy Perry's "Teenage Dream," single "Knock Knock" strays from the ninesome's typical formula and lets new voices shine—like member Sana leading the second chorus. While they explore R&B on "Ice Cream," songs like "TT," "Pit-a-Pat," and "Jelly Jelly" boast the feel-good cheer that's made so many fall for these ladies.
