Vidak recently got a new job as music and production director for a local radio station. However, the digital music library the station uses is unorganized. It's like a jungle. So he needs to be able to organize it with metadata. Leo says that Music Brainz is a great app for that. It's an open-source version of CDDB and FreeDB. It'll open the mp3 and seek to identify the song and album. It'll then add the metadata, and that'll give about 90% of what he will need to reorganize the library. Music Monkey is another.
Jerry has music on his iPhone and he needs a program that understands that there may be multiple copies of the same song (live vs. recorded, etc), but delete legitimate duplications. Is there a third party app that can do that?
