Pandora's shares are on a 6.5% rise today after Goldman Sach's Heath Terry upgraded the company to "buy" with a price target of $27. The online radio service offers streaming radio with ads and then offers a premium version where subscribers can pay to have ad free radio. This allows the company to have two streams of revenue, but to add to it they company has recently put a limit to how many hours of free radio subscribers get for the month which entices them to buy the monthly package where they get unlimited music with no ads to interrupt the listening experience. I WILL TAKE 100 SHARES... thanks
