"Louder" is a song by British producer DJ Fresh. It features vocals from Welsh singer Sian Evans. The song serves as the theme song for the Lucozade Sport Lite campaign. It was released on 3 July 2011 on Ministry of Sound. "Louder" is considered an important landmark for dubstep music as it was the first of the genre to reach number one on the UK Singles Chart. The song was featured on the soundtrack to SCE Studio Liverpool's Wipeout 2048 and used as the promotional theme for Fox8's reality program Cricket Superstar.

The music video for the song was uploaded to YouTube on 23 May 2011. It was shot by director Ben Newman as part of the Lucozade Sport Lite campaign.

Robert Copsey of Digital Spy gave the song a positive review stating:

"Like sipping on a bottle of the electrolyte-infused liquid, its wobbly drum 'n' bass lines are guaranteed to satisfy many a club-goers craving for a three-minute fix of hang-banging, fist-pumping and head-spinning music. "It's gonna get louder," warns guest vocalist Sian Evans on the hi-NRG chorus before breaking into a glorious middle 8 that sounds like a lost '90s classic - prompting the response, 'Don't worry love, keep cranking that dial!'.
