The `Russian Roulette` hitmaker says once she has written a song, she can`t help but start planning every aspect of the track, including promotion, performing and artwork and is unable to switch off at the end of the day.
Speaking about new track `S&M` - which is expected to be the third single off her forthcoming LP `Loud` - she said: "It`s the loudest track on the album. It`s bad a*s.
"And the `S&M` video is going to be totally unexpected. I`m sure people will be surprised.
"Every time I listen to new songs I`m making up videos in my head or thinking about how I would perform it live - that`s why I don`t sleep."
The 22-year-old beauty said the album was inspired out of her frustration that most records have at least one or two tracks she skips past.
She explained to the Daily Star newspaper: "When you go to a club and have to listen to bad music you revert to the liquor because you want to have a good time.
"I hate having to skip a track, especially if I am in the shower. I wanted to make an album you just play."
