Turn on the Shazam app on your phone and watch the latest commercial for American Eagle. Once the app recognizes the commercial's music, you will see a link for a free download of Bruno Mar's Treasure.
The Shazam app is free on both Android and Apple phones. They do offer an upgraded version of the app without advertisements but the free app is great. You can also use it when you hear a good song on the radio to identify the song.
