Months after it became a smash hit, artists are still finding new ways to remix Britney Spears' 'Till the World Ends.' Los Angeles record label Cali Cartel unveiled a new Effe T's Noventas mix of the track that emphasizes low-key electronic synths.

The remix highlights Britney's heavy breathing, using it several times in every line of music. The track borrows the verses from 'Till the World Ends' but actually leaves out the chorus until the 3-minute mark. The "whoa-oh-oh" hook is only used once and is buried quickly, leaving a programmed bass line that we're grooving to.

The Effe T's Noventas Remix isn't the only new track to appear as Spears turned 30 this weekend. A Spears fan site leaked an unreleased older track called 'Love 2 Love U.' Meanwhile, one fan created an intricate domino maze in honor of the pop star, while other artists tweeted their birthday wishes to the singer.

Check out the 'Till the World Ends' remix below. Do you like it better than the Korallreven and R. Kelly remixes of the tune?
