Queen songs that sample other songs and vice versa?

Just a question that has peaked my curiosity for quite some time. I'll be listening to something today on the radio, and it'l suddenly become transparent. Then I suddenly can clearly hear one of Queen's riffs being knicked right off amongst my sensitive little ear lobes. it seems that's the case [here's the gun men come to shoot the messanger] with Queen as well.
I'm not entirely sure song for song, though I was hoping other fellow Queen philosphers could hypothesis this for me.
It seems like a fun little project. I know i'm far too much of a sloth to research every Queen song, and sample other various modern tracks from today. Just to compare the two and draw some conclusion to their connection. It's just far too time consuming.

Minor intricate detail I left out. I meant to say even Queen probably sampled other artists work.

I dont know if this is what you mean but i think Queen took a little bit of inspiration from Video killed the radio Star for Radio Gaga even though Roger said it was partly about something his son said

and we know about Vanilla Ice sampling the bass line ofr Ice Ice Baby from Under PRessure

This is the best resource I've come across:

Joe Jackson's "stepping out" sounds alot like "keep passing the open windows" from The works.
Other than the little piano sentiment sounding similar, they're two completely different songs almost entirely.

==========================

The piano sentiment and the chorus both strongly recall 'Steppin' Out' to my sensibilities.  It's not something I read and then assessed. It's something that  leapt out of nowhere for me on first listen to KPTOW.  It's there significantly enough I think.
