"Keep You" is one of the six songs featured on Monstercat x Rocket League Vol. 3. It is the seventh overall release for Duumu, as well as the debut vocal performance from the duo Sundial. It is a Future Bass track with themes of a toxic relationship contrasted with grandiose future bass melodies.
On the YouTube upload of the song, Monstercat commented: "Duumu gives us a track that can be interpreted and enjoyed in many different ways - love this tune! 💗", possibly referencing the darker ways the song can be interpreted, and the themes of toxicity.
Sundial is the only vocalist duo to have a feature on Monstercat.
