Through their numerous beat-mixed dance compilations, the Happy Boys (aka Robbins founder and president Cory Robbins and VP of A&R and dance promotion John Parker) have amassed sales of more than 1 million CDs. With this latest volume in the Trance Party series, the numbers will surely rise. With ears finely tuned to decidedly mainstream, radio-primed fare, the Boys have a knack for compiling the most melodic, most buoyant and most hook-laden material. Naturally, the set features many tracks from Robbins’ own vault, including DJ Sammy’s “The Boys of Summer,” Lasgo’s “Alone,” Ian Van Dahl’s “Secret Love” and Kate Ryan’s “U R (My Love).” Also making the cut are Gabriel & Dresden’s Unplugged mix of Andain’s “Beautiful Things” and 4 Strings’ “Diving,” among others. Just perfect for that next house party or next visit to the gym.—MP
