This track features Magnetic Man, and according to the NME was originally intended for the dubstep trio's self-titled debut album before being considered "too girly."
Magnetic Man's Benga succeeded in getting Katy completely drunk on sambuca liquer during one recording session. "I just remember being in the vocal booth swaying," she blushed to the NME.
Katy said regarding On A Mission: "It's me, just as a young woman, partying, relationships... the album's definitely where I'm coming from. Tracks like 'Disappear' and 'Easy Please Me' are all experiences in my life and emotions that I've felt."
The song isn't about anybody in particular - just guys in general. Katy told The Sun: "'Easy Please Me' is about how men need to be honest about their intentions and not sleazy or creepy. Most guys approach relationships all wrong."
Katy grumbles on this song: "I love a bad boy mentality/But I don't wanna be visiting no jail." The NME asked her if this had been a problem in the past. She replied: "Look, I don't want a guy who's got an attitude problem but I want them to look after me. If anyone fits that bill then they should, er, write in."
