Alicia Keys and Kendrick Lamar serve up Spiderman soundtrack song

Ahead of the film's May 2014 release, Alicia Keys with a little help from Kendrick Lamar delivers a disco-tinged R&B song called "It's On Again" for The Amazing Spiderman 2 soundtrack.

Definitely hearing echoes of Daft Punk in the production, although it doesn't sound as tight or organic. Lamar's intro sounds ferocious albeit slightly shoehorned in the intro, while Alicia sounds angelic in the refrain. Still feel like it needs an extra kick; maybe more piano? Listen below.
