You have one or more large collections containing audio files? You know exactly that you have several titles double or even triple? But you are not up to fix it on your own because you simply don''t have the time? You want to join misstyped albums or artists quickly without having to sort-out duplicates by inspecting the quality bitrate and so on? You prefer to use drag&drop? And of course the ID-tags should be updated whenever you reassign an album or artist? You have completely untagged or mistagged files and want them to be tagged automatically? While renaiming files your playlists should be updated so they will still work after the cleanup process? You prefer to work with a good performance even if your library contains more than 100000 titles? Using an internet reference database for aligning your archive and research purpose would be great? You would like to have an undo function to revert your changes any time? Some of your music files contain "unreadable" ID Tags because they were created within a different codepage? You would like to convert them to unicode quick&easy? Then you should have a go at AudioExpert!
