Decided to open source my music project I started around February 2010. I will be adding more code to the git repo once I get a chance. Originally I built the project using C#, Asp.net and Flex. But as html5 became more popular, I switched to Java, spring framework, html5, css3, mysql. Currently, I'm considering switching to python, django, and possibly mongodb or hbase. The project is hosted on several Amazon EC2 clusters and I experimented with Hadoop and modified Apache Mahout algorithms for music and concert recommendations.
