"Accelerate" is a song by American singer Christina Aguilera and was released as the lead single from her eighth studio album Liberation (2018). It features guest vocals from singer Ty Dolla Sign and rapper 2 Chainz. The song was produced by Kanye West alongside Che Pope, Mike Dean and Eric Danchick, with co-production from Honorable C.N.O.T.E. and Charlie Heat. In the lyrics, which celebrate living in the moment, Aguilera "accelerates" her sexual partner, wanting him to "show passion" towards her.
Upon its release, music critics were mostly positive towards the track — some complimented it for being "weird", "experimental", and an interesting comeback that "pushes pop music boundaries". The Guardian and Paper both named it one of the best songs of the year. "Accelerate" became Aguilera's tenth number-one song on the US Billboard Dance Club Songs chart. The single appeared on a few national record charts, reaching top ten positions in Costa Rica, Panama and Guatemala, as well as number twenty-two on the Hungarian Single Top 40 chart. The song was included in the set lists for three of Aguilera's concert tours: The Liberation Tour (2018), The Xperience (2019–2020), and The X Tour (2019).
