mistermumbles: This is not really pertaining to this thread other than Bandcamp... anyway, I may have heard the mention of the site before, but this the first time I've actually checked it out, and I really like what I've been seeing/hearing so far. I'm actually quite surprised nothing quite like it has existed until just last Fall. I already came upon three or four artists' albums I'm quite interested in - I spent the last couple of hours just randomly browsing the country/folk section. Very nice. I wouldn't be surprised if I got more into the indie music scene now.
I have a couple of questions though since BC's faq seems to not exactly tell me: It mentioned expired downloads, so is there only a limited amount of time you have to (re-)download the music? Are you stuck just downloading one single audio format or can you download all of them if you so choose? That would be helpful to know before I make an actual purchase.
The download links expire, don't know exactly in how much time or if it's the same for all artists/ albums. But as bcrank said, you can contact support to get new ones (every artist has a specific download-support link on his/ her site).
You can download all available formats. Your download link usually lists mp3, but there's a drop-down menu where you can choose your prefered format(s).
If you check the links I provided, a couple of the albums are free - pick one to see how the download page looks like.
