Congrats, Scotchandcigar!
The answer is Lady Gaga, who has a flair for the macabre in her performances, much like Marilyn Manson, as well as a flair for dramatic costumes much like Elton John.
Also takes influence from the next two clues:
Madonna.
The artist herself was of the opinion that Gaga's 'Born This Way' sounded a LITTLE too much like 'Express Yourself', I'll let you be the judge:
But there is NO questioning that Madonna is major influence on Gaga's music, attitude and overall look.
And the last clue:
Queen's Radio Gaga
Which she takes her stage name from the title of the song. And also lists Queen's music as major influence on hers.
New game next week!
