Grooveshark

Grooveshark is a web-based music application built for anyone on the internet to listen to music on-demand at no charge.

Users have the ability to listen to single songs from the 7-million song catalog, save playlists, and embed both on other websites, blogs, and social media profiles via the Grooveshark Widget.

Grooveshark also allows artists and record labels to promote themselves through the application with both advertisement and paying for listens from Grooveshark users. All data and analytics relating to an artist (or group of artists) are freely available to promoters, such as the number of times their content has been listened to, along with demographic and geographic information about the listeners.
