It also parses ID3-tags, shows songlengths and has limited mouse-support.
mp3album.pl is a tool to automatically create album lists from a batch of mp3 files including ID3v1, ID3v2.2 or ID3v2.3 information. It includes logic to split up all files in one directory into separate albums and generates a report file for each album. The reports are customizable through templates and can contain any information found in the ID3 tags. mp3album.pl lends itself very handy when creating an index of a directory containing several albums of music. As Perl currently lacks 'good' Unicode support, the Unicode strings in ID3v2.3 are not yet supported.
