Britney Spears Teases New Song, 'I Wanna Go'

Britney Spears has released a 20-second snippet of a new song, "I Wanna Go," on Twitter today (Feb. 22), two days after she previewed 10 seconds of another new track, "Inside Out." Along with first single "Hold It Against Me," the two songs are set to appear on the pop star's seventh full-length, "Femme Fatale," due out Mar. 29.

Produced by Max Martin and Shellback, "I Wanna Go" sounds like another synth-heavy dance track buoyed by a whistled melody. In the 20-second preview, a slow build allows the beat to steadily increase before dropping out as Spears sings in a staccato, "I-I-I wanna go-o-o all the way-ay-ay."

"Femme Fatale" executive producer Lukasz "Dr. Luke" Gottwald originally posted a link to the "I Wanna Go" preview on Twitter earlier today, and Spears posted it soon after and called Martin "amazing." Along with Dr. Luke, Martin, Shellback and producer Billboard, Spears has been in the studio with Black Eyed Peas frontman, who wrote that he and the pop star had recorded a new song for "Femme Fatale" together on Twitter last Thursday (Feb. 17).

Although a second official single for "Femme Fatale" has yet to be chosen, "Hold It Against Me" is still going strong: the song remains at No. 10 on this week's Hot 100, and the official music video has earned over 10 million views on Spears' VEVO channel since debuting last Thursday.
