There's some Orchestrated Kingdom Hearts music that's totally awesome (Hikari, Simple and Clean, Lord of the Castle, Darkness of the Unknown, Passion and Fantasia alla Marcia for Piano, Chorus and Orchestra, to name but a few)

Also, the obvious but still awesome Requiem for a dream (Yup, I was the one who'd pull it out the bag
)

And since someone posted the proper version, gotta be some Powerglove in there
Holy Orders (Be Quick and Just Shred) -- Powerglove

Some of the Orchestrated pieces for Tangled are pretty awesome, I highly recommend listening to the Darksiders soundtrack as well, since that also has some brilliant pieces
Edit: Lol, ok the embed failed, but I dunno how to do it properly so I'll put the links at the bottom
