I just noticed today that Grooveshark, one of my three favorite music websites, the others being The Hype Machine and Last.FM, rolled out a new survey platform allowing their users to earn points towards getting a free Plus / VIP account (which is ad-less, and allows for many new cool features like Last.FM scrobbling and a Grooveshark Desktop Application built on Adobe Air, and exclusive preview of other new beta features).
The only survey that appeared to be available was called a Profile survey worth 150 points and I completed it. Hopefully more will be available soon as I’m looking forward to my free Plus account! The site states they email you when new surveys are available.
Just create or log into your Grooveshark account and under the Account button on the top right click on Surveys. Enjoy!
