Oh, sure we do. I mean, I can't talk about her but I have three iPods (one beyon its natural lifespan, one rather old that a friend of mine twice refused as a gift, and the latest about 4 years old). Still, when I'm to work in front of my PC for days softwares like Spotify and Grooveshark come in handy, as I wouldn't have to download and transfer to the iPod the music I'd like to listen to, even out of a whim.
The downside is that the free users like us have no power over the stream quality and the advertising, heavy on spotify. GS is less handy but has no ads and a bigger database.
