First of all, the userscripts site can still be accessed, at least for now, on port 8080.
http://userscripts.org:8080
secondly, if the favourites are being stored on their server, there isn't going to be any way around that... the only thing userscripts can influence is the client side, so unless all the work is being done on the user's computer rather than by Grooveshark's website, a userscript cannot solve that problem in specific. That is, unless some sort of workaround is found.
But can you not just browser bookmark it? That said I don't use Grooveshark so idk
I know that us can be accessed, and I tried several times, but the search function doesn't work. Try searching "grooveshark", which before returned several scripts.
As for the favourites, thanks for answer.
Grooveshark idiotic favourites limit
With Userscripts org down (or malfunctioning) it is difficult to find a good script that fixes Grooveshark. One of many broken features is that users with the free version can only vafourite 500 songs. That is clearly idotic, as one can have more than 500 favourite songs. Even after paying, you are still limited to 2500 i think.
So, does anyone know a script that fixes it, or is willing to create it?
Edit: installing https://greasyfork.org/scripts/1816-pandora-freemium seems to disable the annoying message about not being able to add a song to favourites, but after refreshing the browser, the song is no longer on the list. Sucks.
