Geo::getTopTracks($country) not working

[FFae]

I´m trying to use the function but it is not working.

setApiKey(API_KEY); $tracks = Geo::getTopTracks($country); echo "

"; foreach($tracks as $key => $track) { echo "
• "; echo "Track Number: " . ($key + 1) . "
  "; echo "Title: " . $track->getName() . "
  "; echo "Played: " . $track->getPlayCount() . " time(s)
  "; echo "Duration: " . $track->getDuration() . " seconds
  "; echo "Track URL: " . $track->getUrl() . "
  "; echo "
"; } echo "

"; ?>
