Apple Inc. issued invitations to an event next week that the company indicated would be related to its iPod music players. The Cupertino, Calif., company said the event would be held in San Francisco on Sept. 9. The e-mail invitation, which was sent to media and analysts, showed the shadow of a person with an iPod dancing to music. The words, "It's only rock and roll, but we like it," were printed over it. Apple declined further comment on the event. Apple watchers have been anticipating an event because the company typically unveils its new lineup of iPods every year around this time. The media event will be Apple's first since Chief Executive Steve Jobs returned from medical leave in late June after a liver transplant.
