We are not blocking Pandora. Pandora is blocking us for using an ad blocker. The ad blocker is a Chrome extension. But, fear not you can create an exception in the ad blocker to allow Pandora Radio to play. Or for any other site that is blocking you because of the ad blocker extension.
To do this, you need to go to Pandora.com, you cannot do this from an app or extension, you actually have to go to the site. Go to the stop sign icon next to the address bar as seen here:
The window that opens will look like this:
Where it says block ads on this website, and it says Pandora.com, or whatever site you wish to exclude from blocking ads, click the slider to turn off ad blocking on that site. Once you do, it will ask you to refresh:
Click on refresh, and your site will reload and now be excluded from ad blocker and will function normally.
