Not gonna lie - "This Is How We Do" was the dumps for me -- Katy's worst single, but I genuinely like the Riff Raff remix The subtle production changes make such a big difference. Whether you like the song or not, it actually sounds like a single now (even though there are plenty on Prism, many of which will be sacrificed). For those of you listening to the stream on Soundcloud, you have no idea what I'm talking about.
