Currently Pandora is fighting for its title of the best internet radio service that it has been enjoying really since it was made. Other companies are popping up and challenging Pandora, such as spotify. Spotify is a company that is the biggest challenger based in Europe and expanding to U.S. The difference between spotify and Pandora is that pandora does not require you to have the music so that you can stream it for free, spotify currently for free makes you own the music to stream it, which for most of the computer based users is pointless because it makes it just another Itunes or Windows Media Player but helps the SmartPhone user who streams music from their computer to the phone. Pandora does not offer this service but it does stream any music for free for 40 hours a month. The upgrade in pandora lets you have unlimited and no ads with a few more perks. Currently I would say Pandora is winning the overall battle for the title but I think it is falling as more services come up and pandoras users start realizing it is not the best choice for them. Currently Pandora does have the issue of songs not always fitting in the stations they are put and sometimes sound quality is not the best.
