Guetta hits back after 'button-pusher' jibe

David Guetta has hit back at deadmau5, who called him a "button pusher".
Deadmau5 - real name Joel Zimmerman - criticised Guetta saying he only required "two iPods and a mixer" to perform his live sets, but the 'Titanium' producer has shrugged off the accusations, saying he meticulously learned his craft.
