It was a long, slow climb to No. 1 on the Billboard Hot 100 for Grammy Award-nominated Lady GaGa's debut, "Just Dance," which took nine months to reach the summit in January. It looks as if the second release, "Poker Face," from the album "The Fame," won't have as long a wait. Once again, hooks are aplenty, with '80s-inspired synthesizers, robotic verses and a warm, sunny hook in the chorus, which is even more addictive than the previous single. Already, the track has reached No. 1 in Australia, Canada, New Zealand, Finland, Norway and Sweden. While comparisons abound—Christina Aguilera, Gwen Stefani, Madonna—Lady GaGa has a singular sound and style. With a focused artistic vision, a swagger in her interview style and above all, a fantastic collection of diverse pop nuggets, GaGa is playing her cards right—and "Poker" is another obvious ace. —Chris Williams
