When you find something that sounds interesting - you can listen to the music on the page and get some information about the artist - just enter your email address, country, and postal code, and they'll email you a link to download the music. That's all you have to do. Then simply unzip the file you download and enjoy your new music. If you enjoy it, consider leaving a tip to support the artist and spreading the word through twitter and/or facebook.
You can even embed some music on your website or blog to share with your friends.
I've downloaded several albums, but I don't really listen to music that much, so I haven't even listened all the way through some of them. Unfortunately the option to listen to or sample the music before downloading has stopped working in my browser, probably some plug-in that needs updated. So, I've downloaded some based on the embedded video on the page. Thankfully that still works, and if I like the sound of the song in the video, I'll download the whole thing just so I can hear the rest. And then I don't always do it, but I know there are people who listen to music all the time, so this is a great site for getting some new music - and then being able to support the artists as you choose. You'll also get emails from them once in a while, so you can keep up with the artists you discover, know when they're releasing new music, performing in your area, etc.
