I like the Bandcamp store. You get to pick whichever format you prefer, including FLAC.
Definitely...and ALAC! I wish more bands were on there.
I've got mixed feelings about that. Right now it's loaded with lots of lesser known bands, many of whom I tend to prefer. Lots of very good ones too if you know who to look for. Also, their prices are very good and set by the bands. A lot of free downloads too that bands give away to promote their band; again, in the format of your choice.
If they start taking off too much, I fear it will end up the same way as all the other once great music sites. Too big to manage and eventually sold off to some corporation. Or worse, they close up shop. Once that happens, it's destroyed by extreme commercialism and the prices go up. I love it the way it is now.
