Lets mark this as something I never expected to hear. Christina Aguilera has been MIA for some time, dropping her last album in 2012. She’s gearing up to make a comeback and she starts her campaign with the release of her single ‘Accelerate’. The single – which features Ty Dolla Sign & 2 Chainz and was produced by Mike Dean, Kanye West, & Che Pope – is an eclectic single that fans definitely could not have seen coming. We’re all for Christina pushing her sound though!
