I totally agree, My Only Vice.
Death Trip is, for me, the closest to genius of any of Steve's songs. Reading this post of yours, now over a decade ago, almost makes me capable of me shortlisting my favourite three of his songs...Make Me Smile (Come up and see me), Death Trip and My Only Vice (I think!)
All the best.

P.S. I can't remember where it is now (herein) but I drew the same view of similarity in consideration of BR (Queen) and DT (Cockney Rebel), albeit about a decade after My Only Vice (the mutual fan, that is) did - and I hadn't read his post at that time.
