I want to know the answer to the following question:
What label pushed out Kanye's fourth studio album?
All the background I'm provided with is that "808s & Heartbreak, which features extensive use of the eponymous Roland TR-808 drum machine and contains themes of love, loneliness, and heartache, was released by Island Def Jam to capitalize on Thanksgiving weekend in November 2008.". Is that enough to answer the question?
Answer: yes
