I posted it in the Game 6 thread, but I'll post it again here. It's an empowering song, and also fits the current situation well.
Might as pull the full thing out since it's sampled in Modern Crusaders. Everyone's heard O Fortuna. Definitely read the lyrics, though. They're intense. Sort of thing that just makes you think and gives you the necessary chills as you're about to go out and dance with Fortune. Also, I highly recommend listening to or seeing the whole Carmina Burana at some point. Make sure you have the lyrics. The In Taberna (in the tavern) section is particular memorable. The Houston Symphony puts it on every couple of years. Just saw it a few weeks ago. It's definitely up there in the top echelon of badass classical music. The whole thing. Not just O Fortuna.
Damn...... So many brooms everywhere. So much honking everywhere. So many happy people hugging other happy people.
