“Day 'N' Nite”
"Day 'n' Nite," commonly acknowledged as the stoner jam of 2008, is a simplistic, biographical track by Kid Cudi, a self-professed "lonely loner." "I get sad at the oddest of times," Cudi told Rolling Stone. "I need to see a shrink." Originally released on the rapper's A Kid Named Cudi mixtape, "Day 'n' Nite" attracted a cult-like following and ushered in a new movement of emo-rap, making Cudi a natural collaborator on Kanye West's introspective, synthpop album, 808s & Heartbreak. "[Cudi's] writing is just so pure and natural and important," West gushed to Rolling Stone. Cudi contributed to four tracks on 808s.
