This application does work without a premium subscription and without logging in.

Please note this client is unofficial and using can get your ip banned from groove-shark, although it hasn't happened to me yet.

It is also currently available in ubuntu 10.04 in my ppa

I also have a garage page set up for the project as well

I am still developing this application and I will have an update soon hopefully with radio and playlist support

There are a couple of bugs that I can't seem to get around and they are mostly caused by phonon. I am contemplating using the qtmobility multimedia library instead but I'm not too sure how that will affect desktop performance.

Note: Searching by songs currently work, others like artist and album do not.

I am also doing field tests and found my buffering algorithm is inadequate on cellular networks. Also the bandwidth requirement may be too great for mobile use however I may develop a groove-shark proxy client that would run on your home desktop to reduce the network bandwidth.

I am very new to Qt development and even C++ so don't expect my source code to follow any sort of rhyme or reason.
