This Is How We Do is a bop. The beat, the chorus, etc.
The only reason why people hate it (I assume) is the speaking parts, I found them tacky at first but it's pretty cute now. Plus when the music video comes out, it'll seem better because you'll actually have a visual for it.
Walking On Air would've been a great single, too. Legendary Lovers is so overrated... the lyrics in the chorus alone make me want to fall asleep ("Legendary lovers... should be, legendary!") I remember listening to the album the first time and thinking LL was Katy's worst song of all time, and it actually turned me off a biT. Even though it grew on me by now (and I bought the album months back,) it's still the weakest on PRISM.
