"Big Fat Bass" is a heavily-Auto-Tuned dance track with a lot of repetitive lyrics. "Hey, you see me down on the floor/ I want you to take me higher/ Till I can't take it no more," Britney sings in non-repetitive lines. "And now, you see me up on the sky/ I was rocking the bottom/ Now look at me I can fly."
"I Wanna Go" is also a fist-pumping song, but it adds some whistling sound in the bridge. She once again channels her inner flirtatious kitten, "Lately I been stuck imagining/ What I wonder doing what I really think, time to flow out/ Be a little inappropriate cause I know that everybody's thinking it when the lights out."
