Thanks all.

I'm leaning towards "not". They did have a 6-month offer for $30, which seemed pretty good, but it automatically goes to full price at the end "unless you cancel." I suppose I could just cancel after 6 months - they probably bank on people getting lazy about it. I think costs, after fees and taxes, is in the $14/month range. When you drive the car so rarely (our two trips to CT with it in the past 3 weeks was an outlier), most of the time, I don't even bother to turn the radio on.

I agree about the genre specific. But we have a pretty broad range -- new wave, acoustic singer/songwriters, bluegrass, '90s, BBC, NPR -- on the presets, and I've been hitting the buttons pretty regularly.

Might be time to think about playlists on the iPod, rather than filing everything under "Random Stuff".
