Google Talk installed a plugin into my Windows Media Player client and as far as I know, it was without my permission. Now, they say that this plugin is just to “display the current playing song on my status message”. That is okay, but what I suspect is that they are doing more than that. They are keeping track of which tracks people are listening to (and make an inventory that resonates the “buzz” going around). It would be wrong, I think, to track what songs they are listening to, even if they do so anonymously.
What say you?
