"Filthy" is a song by American singer-songwriter Justin Timberlake. It was released on January 5, 2018, as the lead single from his fifth studio album, Man of the Woods (2018). The electro-funk song was written and produced by Timberlake, Timbaland, and Danja, with additional songwriting from James Fauntleroy and Larrance Dopson. Its music video was released on same day, which is set at a futuristic technology conference and shows Timberlake staging a proof-of-concept demo for a robot. It was serviced to contemporary hit radio on January 9, 2018. "Filthy" debuted at number 9 on the US Billboard Hot 100, becoming Timberlake's 18th top 10 on the chart as a soloist, and reached the top 5 in Canada. Production "Filthy" was revealed as the first single the day after Man of the Woods was confirmed. Timberlake, Timbaland and Danja first collaborated on FutureSex/LoveSounds. All three artists co-wrote the song along with James Fauntleroy, who co-wrote all songs on The 20/20 Experience and all but two songs on The 20/20 Experience – 2 of 2 and Larrance Dopson of production team 1500 or Nothin'. Recording for "Filthy" was handled by Danja and Timbaland. The duo worked on the song in a separate studio, while Timberlake worked between two other studios, which had Chad Hugo and Pharrell Williams of The Neptunes in one room, and Rob Knox of The Y's and Eric Hudson in the other. Timberlake would compose certain sections of the song in his head, as he did in the FutureSex/LoveSounds sessions as well. Danja added screams, moans and breaths into the song, as well as the sound of a lion roaring. While the breakdown was conceptualised by Timberlake - Timbaland and Danja would create the breakdown as Timberlake would sing the melody. Danja also experimented with the idea of hi-hats in the song but felt that they didn't "...feel right. It dates it, puts it into a place of what's happening right now. That's not where you want to be." Composition "Filthy" is an electro funk and R&B song. The song comprises funky electro-R&B elements. Billboard noted the song is a combination of anthemic rock with electro. The track opens with guitar licks, and it morphs into a "sleekly" industrial neo-funk number, complete with synth and a "snaking" bassline. Timberlake speaks/sings tongue-in-cheek lyrics during the track. As noted by Rolling Stones Elias Leight, Timberlake keeps his voice in the middle
