L.A.-based fashion design shop City Rags reports the hottest selling wearables are Classic Rock-influenced.  The Beatles' "Let It Be" album cover sits on top, followed by the Stones' "40 Licks," and of course, "Dark Side of the Moon."  Here's the whole top 10:

1. Beatles ‘Let It Be’
2. Rolling Stones ‘40 Licks’
3. Pink Floyd ‘Dark Side of the Moon’
4. The Doors ‘Strange Days lyrics’
5. Jimi Hendrix ‘Are You Experienced’
6. Grateful Dead
7. AC/DC ‘Highway To Hell’
8. Kiss ‘Destroyer’
9. Led Zeppelin ‘Houses of the Holy’
10. Bob Marley ‘Legend'

It reads essentially like a Classic Rock playlist.  And as we continue to see in perceptual studies and Web polls, Classic Rock's reach has gotten younger as it's gotten older.  More and more, teens and 18-24s are tuning in Classic Rock stations.

One can only hope that in a PPM world, we'll see more and more of this listening manifest itself in rating reports as passive measurement becomes the norm.

Rock on, all you young dudes.
