On-demand: It would be nice if I could find music online without expending so much effort. Of course, I can, really, but I don't feel like paying as much for it as if I went to the record store. I'd like to be able to hear a few songs before buying an album, but if it costs me as much to download the songs as buying the album in the first place, then I've either saved no money or spent twice as much. So it'd be nice if there were programmable internet radios or something like that, where I could tell the empeg what I wanted to hear and it would find it. Preferably while in use -- not as part of some configuration-time activity.
