I'm actually surprised how it's made a partial comeback as it is - there's a few New Wavers, La Roux, The Killers, Ting Tings, etc who have actually had big chart/album success, and even the pop of today (even stuff like Kesha I hate to say) is heavily new wave/80s influenced.
but still it's hard to imagine the genre ever regaining its 1980s glory. what do you think is it possible or does it not stand a chance because of rap and such?
