10 Year Old iPod

The iPod is 10 years old today (a month after the guy who brought it to us, died). My first was a third generation 40GB model which I bought in Tokyo in 2004. It seemed very slim & cool at the time, now laughably  chunky & heavy. After a couple of years the battery gave up and I got the 80GB Classic which I still have. I now have around 11,000 songs on it. To be honest, I don't listen to it as much as I used to, except on the rare occasions I go to the gym. But what to listen to when you tread that mill? For me it's steady rhythmic electronica as opposed to earnest Alt Folk or trip-me-up tricky jazz in 5/16.
