The only thing I hate about Oblivion is the shitty bridge just before the solo. But the other 2 songs have so many sections that I love that they're clearly better.
The start of The Czar kind of drags on for me until the distorted guitars kick in, the only part that is really a standout for me is when that Randy Rhoads style riff comes in.. 'spiralling up through the crack in the sky' and then Jimmy Page solo time. The Last Baron is amazing all the way through.
