I had to think about this for a while, because there are tons of good ones out there. In the end I picked the song "PTtee" by a band called DeeExpus. Not only is the song itself quite good, if you like prog rock, but it is dedicated to my favorite band (Porcupine Tree) and the lyrics are actually about someone attending a Porcupine Tree (=PT) concert and it's full of references that you only get if you actually know PT. Very meta.

Excerpt:

I couldn't take in what I saw
Couldn't believe my eyes
Stage set, effects and mixing desk
Were set to blow my mind
All thru support all I could do was talk
About what would lie ahead
So I went to the stall at the back of the hall
And bought a PT tee instead

We got saddled with guys, yeah me and Bri
Who hadn't seen PT before
"They're the new Pink Floyd apparently?"
Yeah that and then some more
They'd have talked all night 'fi hadn't shone the light
On the Badcat at the back
Was obscured of course cos the band had come on
"Now shut your fucking yap"

Going on and on and on
FOABP's come on


"Sunlight" no where to be seen
But the big screen shined supreme
And as Halo rang out God was in my head
I had a "Halo Right round me"
Anaesthetize and Blackest Eyes
Drown with me the surprise
"And we might not hear our favorite songs"
Yeah there'd be no Trains tonight

Didn't miss it in any shape or form
Made up for by every other song
My Ashes got me so emotional
Yet slammed back to Earth With Shallow

"I'm getting feelings" I know all too well
I'm inspired
And I hope you can tell
