Radionomy, a Belgian startup, is a site that lets you create a free, ad-supported Web radio station

The site, now in beta testing, is designed to make creating a Web radio station trivial, letting you browse through vast music, jingle and content libraries made available by Radionomy. You can also integrate your own musical creations or recordings.

Radionomy also supports a variety of social networking features, including tagging, embed code and station sharing. Here’s an example embed:

Radionomy broadcasts your station free of charge and bears all the costs, including copyrights. Radionomy is supported through audio ads broadcast with the stations. Radionomy offers a revenue share based on your station’s audience.

The name Radionomy come from the merger of two concepts: Radio + Autonomy. The founders of Radionomy thought that Internauts should be able to create radio with full autonomy.
