Mashery Developer Blog

The Echo Nest has launched the first in a series of music API's called Analyze. You can analyze a music file in seconds and get interesting information such as tempo, beats, song sections, and a bunch of other attributes. They have created a pretty cool sample app called "This is My Jam", a site where users can create beat-matched, DJ-quality micro-mixes of favorite songs to share on blogs and social networks. More stuff is coming - keep watching their developer site!
