MoodLogic MoodLogic was a software company founded in 1998 by Tom Sulzer, Christian Pirkner, Elion Chin and Andreas Weigend, and was one of the first online music recommendation systems. The company obtained ratings on over 1 million songs by over 50,000 distinct listeners as part of its proprietary method for modeling user preference space. ==Software== In addition to their web presence, the company created a software application that uses a central database to allow users to collaboratively profile music by mood. Each user has a certain number of "credits" they can use to identify song profiles. Credits could be obtained by either paying for them or profiling songs. This software allowed the user to generate "mood" based playlists based on the mood of the user. The program could also mix a playlist based on a selected song. This would return a playlist with songs of similar tempo, mood, genre, etc. The software was also capable of organizing a music collection based on a "fingerprint" of the song. Moodlogic would generate this fingerprint of the song, upload it to the server and wait for a response. This process could take anywhere from a few seconds to a few minutes depending on computer power, internet connection speed and server load. Once the corrected tag information had been downloaded, the ID3 tag was updated and written to the file. This meant a user could have a collection of incorrectly tagged mp3's and the software would be able to correctly identify, tag, and even organize the songs into folders based on artist.
