beaTunes not only allows you to correct name errors for artists, albums or song titles from the iTunes library, it can also be used to create intelligent playlists generated with a melody used as a model.
To do this, beaTunes needs to first analyze the complete iTunes library: calculating the value of stats like BPM, key and tonality of each song; then filling out the missing metadata from each of the songs.
The playlists that beaTunes creates can use base criteria such as BPM, the key, the year or the genre of the song. The metadata are obtained from the web service MusicIP.com.
Other functions that can be carried out with beaTunes are: find and eliminate duplicate files, as well as locating lags between songs from the same album and year of publication or same artists and genre.
