Certainly she won't be listening to anything by Queen! Brian May (Queen's guitar player) once played guitar on the rooftop of her palace, but when Brian (in the company of Jimmy Page and Eric Clapton) met Elizabeth II a few years later she didn't remember who he was. The following is from The Daily Telegraph (copy-pasted from Brian's website):
It started when Brian May of Queen pointed out that it had been his honour to play the national anthem during the rock concert held at the palace in 2002 to mark the Golden Jubilee. â€œOh! That was you was it?â€ replied a surprised monarch, before moving swiftly on to Jimmy Page.
Quite a lot of people would swoon in the presence of such a talent, but the Queen managed somehow to control her excitement. â€œAre you a guitarist too?â€ she asked of the Led Zeppelin megastar, as if addressing a member of the 1st Haywards Heath Scouts Band. He nodded.
Eric Clapton was taking no chances and, shaking the Queen firmly by the hand, introduced himself by name. â€œHave you been playing a long time?â€ the Queen asked, obviously none the wiser. â€œIt must be 45 years now,â€ replied a non-plussed blues giant.
I guess she's more into trashmetal.
