For me all of them are worthless. I want lossless, which means usually FLAC. And NO DRM. So both Amazon downloads and iTunes are out.
I did buy a FLAC download recently (the new Eno/Byrne collaboration), but there's just not much of that available out there to buy. That leaves getting the physical CDs - most I buy used from Amazon, but not only. Many folks I know use bt for FLAC files, which also comes out cheaper - I don't do that, but there's this question: what to do if you want a particular piece of music that's just not available to buy ANYWHERE, so it's bt or nothing? Questions, questions.
