This self-proclaimed "rappa turnt sanga" invented the R&B robo-soul that's been jacked by every sanga and rappa alive — and he calls out the biters on "Karaoke." But Thr33 Ringz shows what sets T-Pain apart. He's an inventive producer, enveloping radio-friendly hooks in Auto-Tune wackiness. (Check the dizzying crunk-rock "Ring Leader Man.") And he's a love machine, accentuating the urgency of his please-baby cooing with sci-fi effects. The plaintiveness reaches a hilarious climax with "Change," as Pain and Akon offer their plan for fixing the country: "I'd change everyone into a Hershey's Kiss/And we could eat away our fears."
