Napster (NSDQ: NAPS) announced Monday that VP and CFO Nand Gangwani has resigned effective Dec. 31, citing personal reasons. He has been commuting from his Bay Area home to LA for the past four years. Suzanne M. Colvin, VP-finance and corporate controller, will serve as interim CFO while a search is conducted for Gangwani’s replacement. (For good measure. CEO Chris Gorog tossed in a reference to “making strong progress with new and existing mobile carrier partners.”) Release.
