Queen - I Want It All

For Brian May to write such a proud and powerful anthem at the time, especially based on something Dobson said, was a statement of intent - his first marriage had broken up partly due to the affair he was having with Dobson. This caused him a great deal of depression, which seemed to come out in songs like this.

Also considering this was one of the first singles off Miracle, which was around the time Mercury revealed to his bandmates that he was suffering declining health, it has all the marks of a band coming out fighting - the accompanying music video also backs this theme up. See "Scandal" (also on the album) for a similar feel, with lyrics more specifically targeted towards those 'against' Queen at that time - largely the mainstream media.
