Week of May 29

As Memorial Day weekend marks the unofficial start of summer, the charts for this weekend heat up, with six debuts and a brand new No. 1.

At the top is Thompson Square's "Are You Gonna Kiss Me or Not?" That duo's debut hit marks the first No. 1 song by a newcomer since "Animal" by Neon Trees hit the top in December-January. It's also one of three country crossover hits in the top five, with Blake Shelton's "Honey Bee" at No. 4 and last week's No. 1, Christian Kane's "Thinking of You," falling to No. 5.

A couple of country songs enter the survey this week, too, as Darius Rucker matches the four chart hits of his country debut with a fourth hit from the CD "Charleston, SC 1966." "Come Back Song" and "This" both went to the Top 10, and "Southern State of Mind" hit No. 1 the first week of April. "Things I'd Never Do" enters at No. 32.

At No. 40 are two artists whose biggest hits each went to No. 2. Country singer James Otto made his chart debut in the summer of 2008 with "Just Got Started Loving You," which spent three weeks in the runner-up spot. Now he's teamed up with country-pop legend Ronnie Milsap on "Good Thing's Gone Bad." The duet's entry this week marks Milsap's first time in the Top 40 since "Stranger in My House" in 1983. His biggest hit came in the spring of 1981, when "Smoky Mountain Rain" stayed at No. 2 for two weeks.

The week's highest debut belongs to Pitbull, an artist who has been featured in Top 40 hits by Enrique Iglesias ("I Like It"), Usher ("DJ Got Us Falling in Love") and Jennifer Lopez ("On the Floor") over the past 12 months. This time, it's the Miami rapper's turn to be the lead artist as "Give Me Everything" features appearances by Ne-You, Afrojack and Nayer. It enters at No. 30.

While veteran artists such as Stevie Nicks, Richard Marx and Sade all make strong moves in this week's survey, Lady GaGa earns the biggest mover award as "The Edge of Glory" sprints 39-26. Will it be one of the summer songs of 2011? We'll see in the next few weeks.
