It’s a Rails application with a strict requirements on stability and performance under high load. Application can handle high loads using relatively little resources.

This application have been extracted from Yawma. In the process of extraction app undergone a massive refactoring. After that many new features have been added. A few new payment options, BitTorrent file distribution and advanced caching on the view and model levels. Many tasks have been moved into background. For example, music previews generation and album packaging do not block request cycle. Over two years app undergone two major UI redesigns.

The data also could be be exported in CSV, XLS and PDF.
