Pandora is a great music streaming and discovery service, made even better by its integration into the Pokki platform. Also, if you're interested in listening to specific songs, you're probably better off opting to giving the Spotify desktop app a try. You also won't be able to avoid radio ads in between certain songs. The advertising on the side of the Pandora app can be annoying. If you don't like the music comes up on your station, just click the thumbs down button and the app will take that into consideration for future suggestions. You can create stations based on a song, music genre, or specific artist. If you do want to register and have Pandora remember your music preferences, the process is free and simple. You must also be located in the United States to use the service however. Unlike the web-based version, the Pandora Pokki app doesn't require you to create an account to enjoy music from your desktop. Here's how to set up your free Pandora Radio account on your computer's web. The free version includes ads, but you can create custom radio stations and discover new music and artists. Using the Music Genome Project, Pandora will analyze the musical content of the song or artist you vote that you like, and it will play other music that shares some of the defining qualities. Pandora is a personalized music streaming service that offers a free account to be used on any desktop or mobile device.
