16. 50 Cent f/ Young Buck "Blood Hound" (2003)
Album: Get Rich or Die Tryin'
Label: Aftermath, Interscope, Shady
Producer: Sean Blaze
In its heyday, 50 Cent's G-Unit goon squad was a uniquely multi-regional coalition. You had 50, Tony Yayo, and Lloyd Banks from New York City, but there was also Game repping Compton (for the few months before the partnership with 50 exploded into a rivalry) and Young Buck from Nashville. In 2003, Buck and 50 linked up for the Get Rich or Die Tryin' album cut "Blood Hound" to hurl threats over producer Sean Blaze's Timbaland-esque thump.
