38 years ago (March 1986) Queen released “Princes Of The Universe” bw “A Dozen Red Roses For My Darling” released, In the USA 

Freddie Mercury wrote “Princes of the Universe” for the Highlander film. It was included on Queen’s twelfth studio album, “A Kind of Magic,” which also featured other selections from the Highlander song score, in 1986

In terms of musical style, this song is notable for being one of the most hard-edged tracks performed by the band, featuring a bombastic sound reminiscent of contemporary hard rock and heavy metal.

The lyrics are from the perspective of the immortals, about the state of being immortal, the superiority it gives them to normal humans, and the test that they always have to face because of this

This is also the only song on the album in which Freddie Mercury receives solo credit!
“We all have our own ideas of how song should be, because I mean a song can be done in so many different ways, depending on of who is doing it.

The whole thing, I mean, of group policy is, first of all, that the group couldn’t agree on the one single. Because it was to do with the film and also to do with the new Queen product. Because what’s happened – I think for the first time in Queen’s life – is that we actually made a film soundtrack, but we’ve also made a Queen album – so, we had to try to let people know that it’s not just a soundtrack, because we’ve got other songs as well. So it’s hard to depict, that it’s not all one soundtrack, and it’s not just Queen.

We had to try to bring two projects together. And so, I mean, within the members of the band as well, we were fighting as to who liked which song. So we couldn’t agree at all, and basically what happened in the end, we decided there should be two singles, released synchronously in different territories, and because the film is out in America first, we wanted to go with Princes, which goes with the film.

But over here [Great Britain], we released Magic, because we thought that if we release Princes to go with the film, then nobody is gonna see the film here until about July, and they have to know what it means. So, sometimes you have to sort of get that diplomacy, and work out things. So, in America they’ve got Princes of the Universe, over here is Magic…

..To start off, it was a Queen project as such anyway, but we did only, like, five tracks to go in the film, and there’s about nine tracks now… Is it nine? Yes, about nine tracks. So these additional tracks, which are not in the film – so it is a Queen, a new Queen album anyway”
