I use the iTunes store, which I pay for except when I have a gift card, so I suppose I don't stream. I have however used the YouTube to MP3 converter on numeous occasions to convert performances which aren't on albums into MP3s. I don't feel guilty about it. The facility is there, so I use it.

The idea that you only have to buy one or two tracks in iTunes instead of the entire CD is what is so great about it. Later, if you want the rest of the CD, you can get it.
