The idea of Diddy singing in Auto-Tune sounds absurd. But looking ridiculous has never stopped Diddy, the man who made a career out of grossly conspicuous consumption. So he invites a galaxy of stars like Lil Wayne and Justin Timberlake ("Shades") to support him and his Dirty Money duo of Kalenna Harper and Dawn Richard (formerly of Danity Kane). At an hour and a half, Last Train to Paris is way too long, and some of its cuts breach the limits of pretension. Other tracks like "*ss on the Floor" and "I Hate That You Love Me" promise trashy nightlife fun.
