I want to know the answer to the following question:
What was the first song released off of Kanye's fourth album?
All the background I'm provided with is that "Recorded mostly in Honolulu, Hawaii in three weeks, West announced his fourth album, 808s & Heartbreak, at the 2008 MTV Video Music Awards, where he performed its lead single, "Love Lockdown".". Is that enough to answer the question?
Answer: yes
