On June 16 2007, Hey You peaked at #57 on Billboard’s Canadian Hot 100 Singles chart.
The charity single, recorded for the Live Earth benefit, was not promoted to radio and appeared on the chart for a single week only. It marked Madonna’s first appearance on the newly created Canadian Hot 100 Singles chart, which replaced the Nielsen Soundscan chart as Canada’s official singles monitor earlier that year.
Hey You was produced by Madonna & Pharrell Williams during the sessions for the Hard Candy album and is credited to Madonna alone.

Hey You-admirable sentiment-cliched execution!
Such a shocker post-Confessions. Downhill from here
I disagree. Hey You was amazing as was Hard Candy. Have you not head Madame X? This new record is brilliant. I love the fado and reggaeton. Madame X, Rebel Heart and Hard Candy are brilliant.
