Pandora, an American streaming music provider.As one of the selected APPs in the Apple Store, Music and Multimedia Software category, it is dedicated to providing free music and radio to users and has a certain user base in North America.

Pandora offers a free ad-supported service, as well as a subscription-based tier called "Pandora Plus" (renamed from "Pandora One" in September 2015) that also features offline playback support, and more skip and replay.

Listeners can listen to established genre stations, other users' stations, or create their own stations based on their musical interests.

Users can use the thumbs up and thumbs down buttons to declare whether they like a track or not, thus determining whether a similar song should be played on the radio.

Thumbs down will skip a song immediately, but users are limited in the number of times they can skip tracks unless they use one of the paid subscription plans or choose to watch a video commercial.

Pandora is a music app that allows users to create stations based on an artist, song, or genre. Users pick the music they like and it will randomly play songs of similar styles and artists. Pandora can be found on iOS and Android both as a free download. The app has over 40 million active listeners, but also has some strong critics who complain about how Pandora is driving down royalty rates for musicians. However, the app has recently started to promote recently popular artists and songs to help boost profits and advertise for other music creators. The app is fairly simple to use. It allows users to create a station based on any artist. Users can also ask Pandora to create a station for an artist that they like, but are not familiar with. The app then creates a station that plays similar songs. Users can thumbs up or down the songs they hear, which helps Pandora learn their tastes better. The first thing anyone who has downloaded the app will notice was the amount of ads. Pandora allows users to download songs for offline listening, but there are two problems with the feature. 1) It takes up quite a bit of space on cell phones and 2) people are not used to paying for music anymore. So, Pandora needs to have ads be played throughout their app so users are forced to listen through the ads. Pandora also uses an advertising network known as Chorus One.
