Apart from bug fixes, this will be the last version of this plugin.
Since I live in Germany, I am unable to use a Grooveshark subscription. The browser version of Grooveshark is the best I can access, so this is what I might base a potential future version on. Sadly, Hernan from keySharky never responded to my last mails, so everything will have to be written from scratch.
I uploaded the files at multiple hosters in so that they may stay online as long as possible... If one of them doesn't work anymore, let me know in the comments.
