If you're like me you want your whole Amarok music collection rated according to your own personal tastes. Why? so you can play the songs you like more often with those nice dynamic playlists.
Wouldn't it be nice to have a plugin suited to doing just that? Here it is!
To generate from source code you need Rake installed and need to be running
on Linux or OSX.
Then just install the generated plugin file inside Amarok:
Tools -> Script Manager -> Install Script -> (choose generated file)
