For band comparisons: "Billionaires" sounds like Phoenix's "1901" if "1901" had a kept a notebook of writings through high school and college. It's just a little more thoughtful. It's a little bit of The Format and a little bit of The Features' "Blow It Out" (Seriously, the parallels are scary). It's completely controlled bombast. Which is exactly why I'm leaving for California in two days.
Musically, the reason it will remind you of MGMT's anthem is the instantly singable line of "ooo's" in the chorus. Remember the first time you heard the snotty synth-riff from "Kids?" Those ten notes that were non-negotiably going to be stuck in your head. "Billionaires" has the same quality; perfect for mindless singing and moving around. Sign us up. Enjoy your weekend. Happy almost birthday, America.
