Drummer Tommy Lee told Noisecreep
that he feels the song's sound both harks back to their early 1980s work as well as a modern vibe. "It's got a retro Crüe kind of vibe to it - a simplistic riff," he said. "But I also think the song has a modern sound to it. There's some cool analog synths in it and a beat that is really funky and modern. So I guess you can say that it has a retro yet modern sound."
"Overall, I think that 'Sex' sounds like 2012 and that makes me
really happy," he continued. "It turned out killer! Not that I'm not into some retro-sounding stuff, but it is 2012 kids - let's keep it moving."
