Irradiate is a simple app for both Mac and iOS. What it does is simply intercept the connection between iTunes and the server on which iTunes Radio advertisements are stored. When the connection is blocked, iTunes can no longer access the advertisements, and it will just skip them. To get started, download Irradiate from its website. Extract the archive and run the application. Immediately, it will show a popup prompting you to click the “Block Ads” button.

The following popup will verify that Irradiate has successfully blocked iTunes Radio ads.

To restore ads, simply run the Irradiate app again and click “Restore ads.”

That’s it.
