M.I.A.’s long-awaited fourth album, Matangi, will be coming out this spring, the singer revealed in an interview with Australia’s Gold Coast Bulletin."It’s due in April, which is the Tamil new year – April 15th – and I’m still working on it,” she said.According to the M.I.A., her record company delayed the album’s release because they found the sound "too positive.” "I thought I’d finished it. I finished it and then I handed the record in, like a couple of months ago,” she said, noting that she was told to "darken it up a bit.” "It’s like ‘We just built you up as the public enemy No. 1 and now you’re coming out with all this positive stuff.’” M.I.A. said that she was not necessarily complying with the advice. "I’m taking my time to decide what they mean.”With a title that refers to her birth name, Mathangi, as well as a Hindu goddess of wisdom, M.I.A.’s follow-up to her 2010 hit Maya marks her first album with Interscope. "My manager who I fired is now the head of Interscope so that’s also an interesting thing for me – revisiting people in different hats,” she said.
