What is Bandcamp?:
In a nutshell, Bandcamp is a service that allows musicians to easily distribute music online - whether they choose to sell it or distribute it for free - and a website publishing tool. They offer viral distribution for easy sharing and provide musicians with extensive stats reporting so that they can see who is downloading their music and where.
Your Bandcamp Page:
Your Bandcamp page is your home on the service - eventually, they hope to add additional features, like blogging and so on, but as the service stands at the moment, each Bandcamp member has a single page. This page is the home of your music on Bandcamp and is where fans can stream and download your songs. The page design is entirely your vision, so you can set it up so that the design fits with your personal site, and in fact, you can integrate your Bandcamp page into your existing site. This allows you to use the Bandcamp service to sell your music seamlessly from your site without having to set up merchant accounts.
Bandcamp and Your Domain Name:
Every Bandcamp user is initially issued a URL that includes the Bandcamp name, but you adapt your account so that your Bandcamp page has your own domain name. You can learn more about the process here.
File Formats on Bandcamp:
Your music uploads to Bandcamp must be in FLAC, WAV or AIFF format. Bandcamp then converts these high quality downloads into various formats for your fans to download, including mp3. Note that your music HAS to be in one of these formats to be uploaded. You cannot upload mp3 files to the site. Bandcamp's FAQ page can help you convert your music to the correct format for upload.
Also note that Bandcamp does NOT hold ownership rights to any of your music.
