Earlier this year, a video appearing to show Swedish House Mafia press play on a pre-mixed set from a festival performance sparked a debate amongst the biggest names in dance music.
Swedish House Mafia's Axwell defended DJs who just press play during their gigs and festival sets, saying: "In a way, yes, you press a button but you're still there performing your art.
"Maybe DJing is just reserved for people who use vinyl then."
Some DJs have criticised the claims and believe performers should mix new songs live, while feeding off the crowd's reaction.
However, Calvin Harris has insisted that fans just want to hear the hits as they are presented on the album.
"I think it's not a problem," Harris told BBC Newsbeat. "In the club you want to hear a produced piece of music, you want to hear the bass, you want to hear it as good as it can sound.
"I used to perform with a band putting all sorts of work into a live show and I can tell you that the reaction was worse than it is when I'm DJing."
Deadmau5 previously wrote a blog explaining that no DJ can successfully produce new tracks as part of a performance, titling the piece 'We All Hit Play'.
However, A-Trak - a member of DJ duo Duck Sauce - disagreed, saying DJs should put on a show for their fans.
"Questions of authenticity have been raised," he said. "He [Deadmau5] doesn't fully understand, or care for, what DJing is at the core, but that doesn't take away from his talent.
"Crowds used to come see DJs for a musical journey. Now they expect to hear specific songs, and furthermore, they want to see a show."
