If you like Planet Rock, (or Planet RAWWWWWWWWWKKKKKKKKK), have you tried BBC 6 Music?
If you don't have capped broadband, there is loads of content on internet radio -
www.reciva.com lists them all. I listen to
Radio Io It's a bit like "listening to your mate's record collection" - the sort of mate who plays one track from each album, going "listen to this, it's brilliant".
I hope DAB isn't going the way of Betamax, although the sound quality in DV3 is better, I understand. I've got 2 DAB radios, although they only ever seem to get Radio 4.
