The latest app I added to my Ipod is the Pandora app. Pandora is a great web application that plays music you like. You can create custom radio stations to your liking. Just enter a song or artist that you like and it will recommend other songs and artists based upon your music tastes.
Pandora’s claim to fame is the “music genome”. They have people who organize thousands of songs and catalog them by their “genome” . In other words if the song title you just entered has a lot of pianos in the song, it may recommend other songs with similar sounds.
Each song in the Music Genome Project is analyzed using up to 400 distinct musical characteristics by a trained music analyst. These attributes capture not only the musical identity of a song, but also the many significant qualities that are relevant to understanding the musical preferences of listeners. The typical music analyst working on the Music Genome Project has a four-year degree in music theory, composition or performance, has passed through a selective screening process and has completed intensive training in the Music Genome’s rigorous and precise methodology. To qualify for the work, analysts must have a firm grounding in music theory, including familiarity with a wide range of styles and sounds. All analysis is done on location.
They have apps for the ipod touch and iphone. This is one of my favorites for listening to music, check it out at Pandora.com
