The achingly beautiful JLo once again dominates pop culture, this time with her worldwide smash hit “On the Floor” with Pitbull, followed by the Mayan goddess-conjuring “I’m into You” featuring L’il Wayne. The CD continues its pedicure offering collaborations with Lady Gaga on “Hypnotico” and the flashy “Invading My Mind.” Island Def Jam (islandrecords.com). —Nancy Ford
