On Can’t Slow Down, the former Commodores frontman pens a song for every occasion, and the results span the gamut of ’80s pop. An air of unbridled joy and romance permeates everything from the pop-rock synth-boogie of “Running with the Night” to the sweet, slow-dance seduction of “Penny Lover.” While Richie exercises his enviable range (the country waltz of “Stuck on You,” the Caribbean flavor of “All Night Long”), he never loses sight of the fiesta, which promises to outlast the night.
