An Idea.
Would it be possible to make a setting for things to automatically scrobble?
Or have a popup that comes out everytime you open a music-related video asking you to write the music information

Hmm. I don't know about programming. But for example YouTube has categories. Maybe you can make the script identify if it's Music or not because on the video description it will say "Category: Music."

Just a thought.

Of course, I mean this as a setting that people would have to turn on, and use it if they're comfortable with it or if they know they will be using YouTube at that point in time to listen to music only.

I'd prefer a middle ground where it autoscrobbles all videos to a 'saved history' list and then you can look through the list and edit any tags that need attention and then once you're happy they are all correct, you then click scrobble and it sends them to last.fm.

I think the best way to satisfy everyone would be to have a combination of the 2 new ideas and the existing idea as follows

Have an option where all videos are autoscrobbled to a history list (see fusen's post), where tags could be edited and entries selectively removed, before submitting the entire list to last.fm.
Obviously, an entry that is manually scrobbled would not be put on this list, otherwise it would end up being submitted twice.

In addition, have an option after you have successfully manually scrobbled a video, to add it, and the entered tags to a local list.
Every time a video is played on this list (which would be customizable), it is automatically scrobbled to last.fm, ignoring the setting I mentioned a paragraph ago.

I know this would be a lot of work, but it would be nice.
