If you like classical music and care about quality, you should check out Passionato.com (full disclosure: I’m helping them with Web presence expansion). Their terrific download store offers deep, deep catalogue in not only the popular .mp3 format but as lossless .flac files. They have also “soft launched” their blog — if you follow Passionato on Twitter, you will receive autotweets as new articles are posted.
Yes, I’m one of those snobby purist “digiphiles” who insists on lossless downloads. Pristine has been doing it for a while for their own startling restorations of the sort of “historic” performances I crave, and HDTracks already offers a large selection of pop and jazz in high-def flac format; I am predicting Passionato will be the “go-to” site for serious classical fans in short order.
