At the CTIA Wireless conference, Pandora CEO, Joe Kennedy told the crowd that the music streaming service has slammed past 150 million users. This huge mark now makes Pandora the second most downloaded app of all-time in Apple's App Store.

Pandora have high hopes that this is just the beginning, and that with several major deals pending, Kennedy could definitely be correct. Pandora is reportedly trying to get their service integrated into the vehicles of virtually every car maker, just like satellite radio. At the moment, there's no ETA on when, or if this would even happen, or if the company would charge a subscription for vehicle service.

Last year Pandora removed the 40-hour listening cap on free accounts, as well as updating the site's layout with improved features. You can now share stations with friends through a URL unique to that particular station. On top of this, there's a share button for Facebook, Twitter and e-mail to help sharing.
