Updated since 11:59 am EST with stock price.NEW YORK ( TheStreet) -- As Howard Stern ponders his next move, Sirius ( SIRI) chief Mel Karmazin told analysts Thursday that he'd like Stern to stay. Stern's shock-jock humor is one of the biggest draws for the satellite radio shop and a key to improving its slumping subscriber numbers and advertising revenue. Karmazin is more aware of the stakes involved than anyone. Karmazin, who has been selling radio ads since he was 17, took a familiar approach to the Stern question asked by an analyst on an earnings call Thursday. Karmazin gushed praise. Howard "has worked out terrifically well. Bringing Howard to Sirius was a great call," Karmazin told analysts. "In the last four years, Howard has done his best work... helped by the fact that he has a national platform." "He has been a great partner," added Karmazin. "We would like to continue doing business together. There's nothing in his contract that deals with a timeframe as to when we need to negotiate and do a deal. So we have nothing to announce today."
