On January 6, 2000 a group of musicians and music-loving technologists came together with the idea of creating the most comprehensive analysis of music ever.
Together we set out to capture the essence of music at the most fundamental level. We ended up assembling literally hundreds of musical attributes or "genes" into a very large Music Genome. Taken together these genes capture the unique and magical musical identity of a song - everything from melody, harmony and rhythm, to instrumentation, orchestration, arrangement, lyrics, and of course the rich world of singing and vocal harmony. It's not about what a band looks like, or what genre they supposedly belong to, or about who buys their records - it's about what each individual song sounds like.
Since we started back in 2000, we've carefully listened to the songs of tens of thousands of different artists - ranging from popular to obscure - and analyzed the musical qualities of each song one attribute at a time. This work continues each and every day as we endeavor to include all the great new stuff coming out of studios, clubs and garages around the world.
I am not sure where they got the name from other than the site's addictive nature. Perhaps it is a reference to Pandora's Box. That or some geek thought hey this is a great domain name :)
Anyhow be sure to give it a shot, it is free and it has a good mix of music, Stations I have are Casting Crowns, John Denver, Soggy Bottom Boys, Peter Paul and Mary, and Jimmy Buffet.
