UPDATE: According to a release from a 1OAK PR rep, Kanye West samples Jay Z on the track he previewed at the private bash titled "Closest Thing to Einstein" and saluted his longtime friend/ mentor by urging partygoers to join Tidal if they "loved Hov."
He also blasted Taylor Swift for her response to his "Famous" line. West revealed that he gave Swift the heads up about the "I feel like me and Taylor might still have sex" lyric over the phone, noting that the pop star said, 'Ooh Kanye, I like that line!' He then references her recent Grammy speech, adding, “Then she won her award and said something completely different! She not cool no more. She had two seconds to be cool and she fucked it up.”
The video for his full speech can be seen here.
