For questions about the web interface of Pandora, only. Questions about native smartphone apps or other platforms are off-topic here.
Pandora Radio is an automated music recommendation service and custodian of the Music Genome Project. Users enter a song or artist that they enjoy, and the service responds by playing selections that are musically similar. Users provide feedback on approval or disapproval of individual songs, which Pandora takes into account for future selections.
Questions on Web Applications are expected to be about the Pandora web interface.
