Private comments on shared tracks?

The timed comment feature is fantastic! I think it would be great to have an option for a user to keep comments to themselves. When uploading a rough mix for my band to hear it'd be great if I could make notes on my own performance without cluttering up the player.

I can also see this being handy when listening to DJ mix and marking tracks you like - even an option to turn off other users' comments would make it easier to spot a point you wanted to return to.

Yay!
