Pandora's Tesseract

I can't believe I haven't checked out Pandora.com before today. An offshoot of the Music Genome Project, this site will create a streaming playlist of music based on your initial input of, say, a band name, and you can then thumbs-up or thumbs-down the pushed content to further tweak your me-friendly audio output. Warning: it's addictive. Do not operate heavy machinery while using the Pandora service.

So I type in "Mahavishnu Orchestra", and the first track that plays is "Sanctuary" from the Birds of Fire album. Excellent. The next track that comes up is really great too, and is by Chad Wackerman, whose name seemed vaguely familiar (drummer for Zappa, as it happens), but what grabs me is that the guitarist on the track is Allan Holdsworth, which is bloody amazing, since I've never heard this song before, so in twenty minutes time, pandora.com has earned a place of prestige on my Scroll O' Great Things.
