I think he went a little overboard with The Beatles, and yet "Magical Mystery Tour" wasn't even one of his selections. He chose System of a Down's "Toxicity", which I thought was terribly inferior to their first album, and he also "Ritual de lo Habitual" instead of "Nothing's Shocking."
On the other hand, I was happy to see that he picked "Peter Gabriel (3)" and not the insipid "So", and "Led Zeppelin II" instead of "IV."

And I love that he's man enough to choose Alanis Morissette's "Jagged Little Pill", Beth Orton's "Central Reservation", and Liz Phair's "Exile in Guyville."
