MediaHuman Audio Converter is a freeware application for Mac OSX and Windows. It can help you to convert your music absolutely free to WMA, MP3, AAC, WAV, FLAC, OGG, AIFF, Apple Lossless format and bunch of others.
This tool is aimed at people migrating a music library from iTunes™ to Foobar2000, and allows you to keep the various statistics and dates that are saved by iTunes. It reads these fields from your iTunes Library XML, and writes them to the file tags that are expected by the import function of foo_playcount. You can transfer playlists too.
