The DJ and producer has been a key figure in bringing commercial dance to the US charts through his tracks with Black Eyed Peas, Akon, Snoop Dogg and Flo Rida, among others, and is glad more people are catching on to the sound.
He told news.com.au: "House was underground for so long. I always wanted house to be as big as rock music and hip-hop. And it's happening. It's even bigger. I'm not only happy for myself but for the house community."
However, David was recently angered when an unreleased version of his track 'Titanium' was leaked, featuring vocals by Mary J. Blige, rather than Australian singer Sia, who originally sung the track as a demo, but David had liked it so much he selected it for the official release.
He said of the leaked song: "You shouldn't even know about that. I'd rather not speak about it. That was annoying. It wasn't supposed to be out there.
"The first time I heard what Sia did I fell in love with it. I didn't even want to give it to anyone else; it was perfect the way it was. It's not only about how big you are in America, it's about the song and the voice."
David's 'Nothing but the Beat' album is out now.
