tumblr is like a combination of tweeting, blogging and social networking. Some people would probably refer to it as a form of micro-blogging. You can post a single song, a single video, a quote, answer and ask questions, etc.
It is similar to a blog or twitter in the way that you can filter results by tags and subjects. This way you keep up on the tumblr world with only what you care about. I just really started using it today, but in addition to this site, I will be fairly active on tumblr if you prefer to get your music that way. However, don't forget to come back here to the main page often, because there are lot's of exclusive downloads via the main site.
