Dance music class of 2009, behold your homecoming king and queen: A man named Guetta and a lady called Gaga.

David Guetta, the DJ from Paris, and Lady Gaga, the pop phenomenon from Yonkers, N.Y., brought some order to the dance/electronic charts this year, with releases that ranked high across all three major charts–Dance Airplay, Hot Dance Club Songs, and Top Dance/Electronic Albums. The triple-threat confirms the pair as dance’s first endemic superstars in years.

Powered by a high-profile performance on Fox’s “So You Think You Can Dance,” “When Love Takes Over,” Guetta’s anthemic collaboration with Kelly Rowland, took No. 1 on the Hot Dance Club Songs chart and No. 3 on Dance Airplay. “Sexy Bitch,” a club banger featuring Akon, also hit No. 6 on Hot Dance Club Songs. Both tracks helped power Guetta’s “One Love” (Gum/Astralwerks) to No. 19 on the Top Dance/Electronic Albums chart.

But Guetta’s biggest hit of the year is The Black Eyed Peas’ massive “I Gotta Feeling” (No. 15 on Dance Airplay and No. 4 on Hot 100 Songs), which the DJ co-produced remotely with via email swaps. In between launching the pantless trend and bringing gore back to MTV this year, Lady Gaga got more chart mileage out of 2008’s “The Fame” (Streamline/KonLive/Cherrytree/Interscope/IGA). The album hit No. 1 on the Top Dance/Electronic Albums chart; and power-singles “Poker Face” and “Just Dance” (in its second year of chart dominance) took No. 2 and No. 12 on Dance Airplay respectively. “Poker Face” also bet its way up to No. 16 on Hot Dance Club Songs.

Beyond Guetta and Gaga, dance continued its age-old support of female vocalists with high Hot Dance Club Play Songs chart finishes for stalwart Deborah Cox (No. 3) and upstart Erika Jayne (No. 5). Even Katy Perry scored big with “Waking Up in Vegas” (No. 2), thanks more to her remix team (Jason Nevins especially) and club-friendly subject matter than the original song itself. The Pussycat Dolls had two of the other Top 10 club tracks of the year, with “I Hate This Part” (No. 7) and “Hush Hush” (No. 10).

The top dance albums of 2009 were the usual collision of pop (Lady Gaga at No. 1), compilations (DJ Skribble’s “Total Club Hits 2” at No. 6), and popular releases over a year old (the “Slumdog Millionaire” Original Soundtrack at No. 2 and “Want” by 3OH!3 at No. 3, both originally released in 2008). Genre heroes Depeche Mode and Imogen Heap finished at No. 5 and No. 7 with their strong, if not hit-generating releases.

Over on the Hot Dance Airplay chart, one single showed a level of stamina usually reserved for albums: Finnish producer Ercola’s undeniably hooky “Every Word” finished last year at No. 5 and this year at No. 7, holding even stronger than Lady Gaga’s seemingly omnipresent “Just Dance” (No. 3 in 2008, No. 12 this year).

But the biggest one-off win went to dance veteran Kim Sozzi, whose “Feel Your Love” overtook Guetta’s “When Love Takes Over” to score a Dance Airplay No. 1, the artist’s first. The pretty, dewy track proved that singalong vocal trance has a place on every year’s round-up.
