Pandora is available on everything -- as an app for your phone or tablet from your App Store, as a channel in smart TVs and streaming boxes (like Roku and Apple TV), or as a web app or web page on computers and Chromebooks. Pandora lets you enter an artist's name, or a song, or even a genre like "Show tunes" as a seed, and it creates a "station" that plays the artist and/or song along with similar music.
Pandora lets you create up to 100 "stations" and you can refine them by adding artists to a station, and by using the thumbs up/down to help Pandora know what you like. Once you've created your free account, Pandora will give you your stations on any device you use, so you can get your stations on your smartphone as well as on your computer and/or tablet. If you want to go ad-free, or be able to skip songs more than 12 times in a 24-hour period, you also can subscribe for $4.99 a month.
