West and Wu-Tang Clan's Raekwon lay down PG verses, while Justin Bieber's soaring R&B vocals from 'Runaway Love' are paired nicely with clunky piano melodies in the song's hook: "Searching low and high, know that I'm not giving up / I'd give it all up for us (never be enough) / (I won't stop until I find) my runaway love."
Meanwhile, Rae's opening lines are fierce: "You got stacks like the International House of Pancakes / All alone, ready to phone me and your hand shakes / Palms is wetted, don's regret / Never to walk miles for love, I sit in the starter's deck."
Born out of the tweets between West and Bieber, the 'Runaway Love' remix manifested just weeks later. Raekwon took up Kanye's invitation and flew into New York City last week to add two verses to the remix. Hours after the song leaked on the Web -- littered with DJ stamps -- Kanye announced the remix on Twitter.
