Much like her earlier material, XS is a 2000s-inspired track that takes influence from classic R&B anthems. Lyrically, however, the song is grounded in present day, tackling issues such as capitalism and climate change.
In a statement, Rina said XS is a “song that mocks capitalism in a sinking world” and that her aim was to draw attention to how “global climate change is accelerating and human extinction is a very real possibility within our lifetime”.
