Yes of-course but I'm still pessimistic about it.
Yes your classical music can be in full-res/hi-res now - DG eg. have full-res FLAC downloads, and Classicsonline as well.
But pop, and even rock music? I mean, and no offence to anyone here, is your Lady Gaga listener really interested in lossless?
Labels of popular bands like Pink Floyd still don't make full-res downloads available. Maybe someday in iTunes. Even Beatles - well you have to buy the entire catalogue to get it.
Hi-res radio streaming will not happen in the near future, I don't think. Bandwidth is still a problem, and really, who cares? If you like a certain album you're still gonna buy it.
