The last 20 tracks broadcast forth from my Harman/Kardon speakers (from iTunes Library on shuffle) were:

• Gil Scott-Heron – Did you hear what they said
• Billy Joel – It’s still Rock and Roll to me
• Ike & Tina Turner – Nutbush City Limits
• Kylie vs Moloko – Bring it back in your eyes
• Broken Social Scene – KC Accidental
• The Chemical Brothers – In Dust We Trust
• Gary Moore – Jumpin’ at shadows
• Suede – Trash
• Morcheeba – Can’t stand it
• Bob Dylan – Oh, sister
• Dannii Minogue – Put the needle on it
• The Drifters – Kissin’ in the back row of the movies
• White Stripes – Let’s build a home
• Madonna – Intervention
• The Beatles – Yesterday
• Deltron 3030 – Battlesong
• Sly Stone – Stand!
• Jackson 5 – Blame it on the boogie
• Blur – Mellow song
• Tom Petty – Free Falling

Hmmm surprisingly free of rock music really, considering about 70% of my MP3s are of that genre.

And for the record: I disagree with people limiting this meme to a playlist (e.g. limited choice) it should be your entire library – all or nothing people, all or nothing!
