Grooveshark is a web app that allows you to listen to music on-demand through the Internet without any charge (it requires only a Grooveshark VIP subscription for $3/month). The song can be chosen from the gigantic 7-million song catalog.

Grooveshark creators claim it supposed to be released in App Store but it wasn't because Apple has been "ritually rejecting" the app for "primarily selfish reasons". TechCrunch reports there were spent months of waiting for Apple approval. After Grooveshark's patience gave out they decided to release its iPhone application via Cydia.

From now on you can download it from the Big Boss Cydia Repository.
