 Chuck Taylor from Billboard also praised " I 'm Your Angel , " a duet with R. Kelly . He wrote that " this wonderfully restrained ballad delights with the most graceful vocal performances either of these artists has ever offered to radio . " Taylor commented , " what raises the roof is the tune 's elegant , epic instrumental base , which includes sweeping strings , a soulful choir , and gentle but determined percussive drive . " He continued , that " I 'm Your Angel " " sells big at the bridge , where the instrumentation drops and Kelly and Dion harmonize in a gorgeous minor key – it truly makes the song . " Chuck Taylor also reviewed " The Prayer " , calling it " a breathtaking , ultra @-@ lush song , and the tour de force combination of Dion and Bocelli [ which ] will send a half @-@ dozen chills up your spine . " Although he felt that the song is " an unorthodox track for the radio " , Taylor called it " affecting , " " heartwarming , " " absolutely exquisite " and " one of Dion 's most radiant performances ever .
