Ariana Grande’s 'Sweetener' is less than four months old, but the pop star has already been hinting at the release of a new project. Her recent single, “thank u, next” may serve as the new album’s title track. Recently, she premiered the video for her 'Sweetener' cut “breathin,” which continues to climb the charts after initially peaking at No. 22. The video contains a brief shot of a train arrival times board, which spells out several words that could be track titles.
