Flash listening to music while on Monitor duty was not really unexpected. In fact, it was an unwritten rule that, if you had had a bad day (and weren't the Bats doing your patented Bats!Emo time), all you had to do to cheer up was talk to Flash- or watch him while he was on monitor duty, and this day was no exception.
John Stewart aka Green Lantern aka "GL" had had a bad day.
And he had monitor duty with Flash.
He was late (some bank-robbers, no big, but he was the closest), and when he got there he found that Flash had put on an older song, and was singing along.
Flash a-ah
Savior of the Universe
Flash
He save everyone of us
Flash
He's a miracle
Flash
King of the impossible
GL started to grin, then to laugh silently. Flash didn't hear him, and instead kept singing along to the song.
He's for everyone of us
Stand for everyone of us
He save with a mighty hand
Every man every woman
Every chill-he's a mighty
Flash
Superman came up behind him, wanting to watch Flash too. He was smirking as both men watched the scarlet speedster.
Just a man
With a man's courage
Nothing but a man
But he can never fail
No-one but the pure at heart
May find the Golden Grail

"You know that that song is about Flash Gordon, right?" GL asked, a grin on his face. Flash jumped and spun around.
"Supes- GL, what are you doing here?"
"Did you forget? It's you and me on monitor duty today." GL reminded the younger man.
"And you Supes?"
"I just like that song."

"Anyway, you two have monitor duty now, so I'll leave you alone."
"...I hate you two." And monitor duty commenced.
"So, who's the lucky lady with the 'Flash- I love you! But we only have fourteen hours to save the Earth!'?"
"... Screw you GL."
