MP3 is a horrible non-free (well, not anymore, because the patents expired; but still), outdated format. bandcamp also lets you download as FLAC, which is none of that and lossless.

edit: it feels this comment came off a bit aggressively, so I just wanted to say that wasn't my intention 😅

Ah, didn't expect you to already know qobuz 🙃

But yeah, that's definitely a problem. I remember them sending the email where they announced this could happen now (although weirdly enough, they never sent an email for when purchased items were taken down any time after that again), and had it happen a few times as well. Luckily, I've also saved everything locally, so I haven't lost anything. Still annoying. Also sometimes, an album that's suddenly gone just seems to reappear a few months later, as if they were just reorganizing their library, but really, I have no idea what's going on.

Didn't know about them before, thanks for sharing!

The same album might be sold lossless in one region and only lossy in another region.

That's weird, since as far as I can tell, qobuz doesn't offer lossy downloads at all (I've heard they used to, but stopped. Maybe there are some regions where they're still offering it?)
