Pandora: simple, instant, responsive

I've been testing out Pandora
the last couple of evenings, as my sister still hasn't yet replied to
my email asking her to recommend some new CDs I should get (hello sis!
;-)

I love the interface to this service: simple, instant and responsive.

And I've even got a couple of decent recommendations out of it which I've decided to buy. Pandora went live Aug 29
