Last.fm Tag Feature Improvements

The tag feature is pretty cool, but why limit it to just songs? I was thinking at the top of the tag popup it says "Artist | Album | Song" and you can click which one you would like to tag. When you think about it, it's incomplete as it is now. This would also make tagging much faster (and thus helping last.fm get some not crappy tags!)

This ones a stretch but I had the thought of a tag cloud instead of the list. Like how it used to be on artists page.

If anyone else has ideas about the tagging feature, please post :)
