Cons

Con Not available outside the US
For those that live outside the US, the service is not available to them, which greatly limits users from around the globe.
Con Limited bitrate
Most songs played on Pandora Radio are 128 kpbs bitrate. That being said, the paid version of the service offers songs with a bitrate of 192 kbps.
Con Limited skips
Pandora makes it very difficult by limiting your playlist to only a specific song or artist. The player also does not allow you to rewind or repeat any songs.
You are only granted six skips per station per hour, and even this is limited to 72 skips per user per day. This is often frustrating if you are trying to focus your playlist on a very specific music selection.
Con Rips artists off
Only Youtube pays artists less than Pandora. Spotify has been under fire for not paying artists enough, at $0.0044 / play (as of march 2018). Well, Pandora pays less than 3 times that! ($0.0013). Tidal pays artists roughly 10 times more ($0.0125).
Con Frequent advertisements
The free version of Pandora has frequent audio advertisements that are injected every few songs, making the service impossible to use in a party-type setting. However, these can be avoided by paying for the premium edition or by using other ad-blocking software.
Con Limited artists
There are only 1 million songs on the service. This means there are a lot of artists missing.
Con Limited genres
For the available genres the user can pick from, there are only so many listed. Any more fine grained controls of being able to play genres not listed is not supported. This means the eclectic and more niche genres can only be played by directly selecting the bands that play that style of music.
Con Only uses the Soundcloud music streaming service
There is no way to get other licensed music, you can only play what is available on the Soundcloud music streaming service.
