No, I would love to. I don't own a lot of digital music. Some things of Jewel, I always make an exception for her off course.
Heather Nova had a good strategy. After her concert you could buy the concert the next day on her website, after that you would get a download link. she did that every evening on her tour. I think that made her some extra money. So I also own one concert of her digital, but that's about it.
I own a view downloadlinks from albums (you get them for free when you buy a LP sometimes) but I never downloaded them yet. I Should do that sometime.
