Though I did overhear an extended conversation about Zeppelin today--and about "Rock and Roll" in particular--I have none on my iPod. Instead:

1. 'I Summon You,' Spoon
2. 'Unsuffer Me,' Lucinda Williams
3. 'April 8th,' Neutral Milk Hotel
4. 'Don't Forget Where U Came From,' Dead Prez
5. 'The World Stops Turning,' Ted Leo/Pharmacists
6. 'Motor Away,' Guided by Voices
7. '8 Million Stories,' A Tribe Called Quest
8. 'Crazy,' Willie Nelson
9. 'Winter Must Be Cold,' The Apples in Stereo
10. 'Back to Black,' Amy Winehouse
