The latest in über-pop darlings is California singer, songwriter, and actress, Bonnie McKee — whom DJ Kalkutta turned us onto last month, here. As Kalkutta told us in May, McKee, "literally pop royalty," co-wrote smash-hits like Katy Perry's "Wide Awake" and Taio Cruz's "Dynamite." And now, McKee's highly anticipated track, "American Girl", has just hit YouTube. After listening, we're more than comfortable saying this tune takes the cake in the song-of-the-summer running: It's bouncy, rhythmical, and extremely catchy, sounding akin to Katy Perry and Ke$ha, among other queens of the pop field. We suggest you watch the video now before it hits the big leagues, so you can say you heard it first!
