I'm afraid you clearly don't understand the situation.

If you sign away the rights to your work, or use of your work to a company or individual it can be difficult or impossible to get those rights back.

To use the track 'Heart of Gold' in a film, the film's producers have to get permission from Young. That permission comes in the form of a license to use the track, and that license covers usage in the film itself, promotional material and any spin off merchandising such as soundtracks, dvd/blu-ray releases and video games.

And of course, we don't know what's going on behind closed doors. Young may be negotiating the removal of the rest of his music even as we speak. But these negotiations can be lengthy and sometimes very expensive.

Ignoring facts, making assumptions and sweeping generalisations will not win you any arguments.

Certainly not this one.


PS - I understand *some* science very well.
