It's hard... and I'm a very new Queen fan... but I certainly love Crazy Little Thing Called Love and Bohemian Rhapsody. I love watching Play the Game, but I guess the other two are better. This one is so 80's... but I love it anyway :). I'm Going Slightly Mad is brilliant too.
I'm generally not a big fan of music videos, but I like all the late Queen videos (except The Invisible Man - a horrible, childish video with pathetic computer special effects from the 80s). I think Freddie looks great with the beard he had in all the videos of The Miracle, and all the Innuendo videos are beautiful too. Days Of Our Lives is my favourite as it was Freddie's last, it's so poignant. I also like the Made In Heaven films by the British Film Institute.
and It also tells the whole story perfectly, before Freddie enters the house, the others are just drunken losers, Freddie Magic makes them all stars, and after Freddie leaves the others fall back to be losers again
I wonder if Freddie himself wrote the storyline, and no-one else realized what it means?
