The earworm this month is not a single song but rather the discovery of a band. They're called Concorde, they're French and they sound a bit like The Strokes or Phoenix jamming on happy new wave bass lines that fit right into the 2000s electro-pop movement.
I came across them on Garance Doré's blog and more specifically the Hello World web series she did in collaboration with J. Crew. Their upbeat compositions make for a perfect soundtrack and I've been hooked ever since.
You can listen to their songs on their youtube page.
