Task: Question Answering
Input (English): Passage: "Déjà Vu" debuted to mixed and positive reviews among critics. Mike Joseph of the international webzine PopMatters' believed that it was "fantastic to hear Beyoncé singing her lungs out over a full-bodied groove featuring live instruments". Spence D. of IGN Music, a multimedia news and reviews website, complimented Jerkins' bass-laden groove, writing that it brought the track to perfection. Describing "Déjà Vu" as a magnificent song, Caroline Sullivan of The Guardian complimented Beyoncé and Jay-Z collaboration calling it "feverish as pre-watershed pop gets". She added that even though when Jay-Z is not physically present, he manages to bring out something formidable in Beyoncé that evokes "the young, feral Tina Turner". Bernard Zuel The Sydney Morning Herald praised the assertiveness with which Beyoncé delivers her lines and considered buying "Déjà Vu" as worthwhile.Several other music critics have compared "Déjà Vu" to Beyoncé's 2003 single, "Crazy in Love", the lead single of her debut album. According to Gail Mitchell of Billboard magazine, the song is viewed by many as a sequel to "Crazy in Love". Jason King of the Vibe magazine deemed the song as "cloned from the DNA of the raucous 'Crazy in Love'" while Thomas Inskeep of Stylus Magazine referred to it as "'Crazy in Love' lite". Some reviewers, however, were negative to the parallels drawn between the two songs. Andy Kellman of AllMusic, an online music database, wrote that "['Déjà Vu'] "had the audacity to not be as monstrous as 'Crazy in Love'", referring to the commercial success the latter experienced in 2003. The internet-based publication Pitchfork's writer Ryan Dombal claimed that "this time [Beyoncé] out-bolds the beat".Sasha Frere-Jones of The New Yorker deemed the lyrics as a "perplexing view of memory", while Chris Richards of The Washington Post characterized Beyoncé as a "love-dazed girlfriend" in the song. Jody Rosen of the Entertainment Weekly referred to "Déjà Vu" as an "oddly flat" choice as a lead single. Jaime Gill of Yahoo! Music regarded "Déjà Vu" as a good choice for a single but concluded that it does lack "the kind of killer chorus" to suggest that Beyoncé would take one further step "to outright global domination". On the other hand, Jon Pareles of The New York Times wrote that Jay-Z shows up "as calmly boastful as ever" in the song but he only makes Beyoncé's "sound more insecure". Kelefa Sanneh of the same publication noted that "the refrain doesn't give Beyoncé a chance really to show off" and further described the song as a "fair-to-middling single from a singer who is the opposite of desperate".
