Pandora is free personalized internet radio. Simply enter a favorite artist, track, comedian or genre, and Pandora will create a personalized station that plays their music and more like it. Rate songs by giving thumbs-up and thumbs-down feedback and add variety to further refine your stations, discover new music and help Pandora play only music you love.
Pandora is powered by the most comprehensive analysis of music ever undertaken, the Music Genome Project: a project started over ten years ago to capture the complex musical DNA of songs using a large team of highly-trained musicians.
Pandora is always free, with the option to pay for additional features (Pandora One).
