My favourite track on the Femme Fatale album track is 'I Wanna Go' - it's just been confirmed as the third single release, so I'm going to be interested in buying any remixes.
The lyrics refer to her past breakdown and how everybody is now watching her closely, waiting for another blowout. She is simply saying that she wants to kick back sometimes, have a bit of fun and let of some steam without people jumping to conclusions all of the time.
The producers use what sounds like a recording of someone whistling to accompany the music in the bridge, which hooks me in - very boho. Critics and fans [via various polls] agree that this is a standout track, so the single release was no surprise.
