Listening to your favorite online radio stations is also possible. The focus is on having fast control of all your music.
Flac-utils is a toolkit for managing FLAC files. Its primary usage is syncing metadata between sets of FLAC files. Flac-utils also provides a Python module called flac_compare that can be used separately. The utilitiy consist of three tools: flac-sync, which syncs a file tree of FLAC comments for files with the same audio-part; flac-diff, which compares two FLAC files' metadata information and shows the differences; and flac-add-picture, which adds album cover art to the files using Amazon.
Audio::BunnyMusicFile is a Perl module for working with a music collection in a high-level way. It supports the decoding and encoding of music files, tag editing, and naming based on file properties. The behaviour of the module is controlled through a flexible configuration file, allowing consistant behaviour between user applications.
musutil includes several utilities for working with a music collection. The principle one is musview, which generates a number of "Views". Each View, analogous to a database view, is an alternative presenation of the original files. The View can selectively include only some files (based on their properties) or have files processed into into a different format, with audio filters applied, adjusted tag data, or a different filename.
Peyote is an audio player with a friendly MC-like interface. It is designed specifically to work easily with cue sheets. It plays wv (wavepack), WAV, FLAC, APE, Ogg, WMA, and MP3 formats. It supports ID3v2, APEv2, FLAC, and Vorbis tags; multiple playlists; and tabs. It can copy, move, remove, and rename files.
puddletag is a tag editor for Linux loosely based on mp3tag. It uses a table layout so that all the tags you want to edit by hand are visible and easily editable. puddletag excels at automating repetitive tasks like extracting tag information from filenames, tagging files from a text file or the clipboard, renaming or moving files and folders based on tags by using patterns, and manipulating tags using actions and regular expressions. Supported formats include id3v1, id3v2 (.mp3), AAC (.m4a), VorbisComments (.ogg, .flac), and APEv2 (.ape). Much of mp3tag's functionality has been replicated with added enhancements and tweaks.
Flac2All is a multi-threaded script that will convert your collection of FLAC files into either Ogg Vorbis, MP3 (with the Lame encoder), or FLAC, complete with any tags and identical file/folder structure. The script has been stable for about a year now, and it has been known to saturate 8-core machines with parallel conversions. It is useful for people with with large FLAC collections who also want a lossy version for portable media players. If wanted, the script can perform updates by skipping already converted files. It has only been tested on Linux, but it should work without alteration on the other Unix systems with bash and the required dependencies.
Klactoveedsedstene is a cross-platform graphical audio front-end to MPlayer. It has advanced support for album art. It recognizes embedded album art, and is also mostly able to find the correct album art from the Internet based on the Metadata tags. It features fast startup, Select and Play, an all-in-one window, and the ability to drag and drop music into the library. It supports ape, FLAC, Ogg, MP3, MPC, WAV, and WMA. It is highly configurable and stateful (remembers your window settings). All parts of the GUI can be colored. It has Album-Artist-Track view. All track columns are sortable and movable. The interface can be minimized.
