Queen/Awesome

How many rock singers have performed in sold-out stadiums? Some. How many have performed (in this case, pre-recorded the performance) a song for the Olympic Games? "One."
Their one true Moment of Awesome, though, is their appearance at Wembley Arena during Live Aid, in 1985. Freddie Mercury took a hundred thousand people into the palm of his hand and led them to heaven. Their set during the Live Aid event was recently voted the Greatest Live Gig By Any Band EVER, and there have been very few dissenters from this opinion. (They obviously haven't seen Freddie in action.)
- Almost a year later, Queen returned to Wembley for a show all their own, which became another great example of Freddie making that whole stadium his bitch.
Freddie's Dying Moment of Awesome: Brian was worried that Freddie might be too sick to do justice to "The Show Must Go On." Freddie nailed it in one take.

Basically all of it, but "Bohemian Rhapsody" is certainly the most evocative.
- "Bohemian Rhapsody" was Queen's younger Awesome Music. Their older one was definitely "The Show Must Go On."
- That latter one can destroy planets.
Tolga Kashif wrote a symphony based on Queen's music. It is a solid hour (well, 58 minutes) of sheer auditory awesome.
"HEEERE WE ARE! BORN TO BE KINGS! WE'RE THE PRINCES OF THE UNIVERSE!"
The March of the Black Queen manages to exceed even Bohemian Rhapsody in awesomeness and crowningness.
"Radio Ga Ga," full stop. Might possibly double as a Heartwarming Moments, as it's basically one big ode to radio.
- Big YMMV on "Radio Ga Ga", some consider it one of Queen's more dull songs.
We Will Rock You/We Are The Champions, uplifting and empowering to almost everybody.
Under Pressure, mainly for two reasons: 1, it's a collaboration between David Bowie, the other major Glam Rock act of the era, and 2, the incredibly high note Freddie hits in the middle.
