Organizing your music: Tagging as you rip

I think that I've always hated filing and organizing stuff. Equally, I always hate it when I can't find something because I haven't filed or organized it well. When it comes to enjoying my music, these two contradicting tendencies tend to show up when I try a new music player that can't figure out how my cover art is stored, can't find the correct cover image online because the album is unusual, or the version I have isn't correctly named. Unusually for me, though, I have invested a fair bit of time (grumpily) in trying to organize my music,meaning I structure it well on disk and make sure the tags and cover images are consistent.

Lately, as I've been exploring new players and new playing environments, I have had the chance to try a few different music tagging applications. I've summarize my experiences so that others might benefit.

What is a music tag?

Before diving too deeply into the why and how of tag editing, consider what a music tag is and why you use it. Any given tag is data about the music contained in the file, which makes it metadata.

Wikipedia's article on tag editors mentions a substantial number of music formats and on the format of tags themselvescarried within those formats. The site's open FLAC music format article tells us that FLAC "uses the same system as Vorbis comments" for storing metadata. Wikipedia's Vorbis comments article further informs us that tags are intended to store short Unicode strings as well as (binary) cover art. The general format is FieldName=Data . As for the MP3 format, its tags are stored in ID3 format . MP3 is not really open, although it is commonly treated as such and has had some its patents apparently expire (see the section Licensing, Ownership and Legislation ). And by the way if the description of patent shenanigans in that article aren't enough to convince everyone to start using FLAC or Ogg Vorbis, I'm not sure what is.

Besides all that technical stuff, music tags or metadata are put there for our convenience, so each file carries around enough info to identify itself. Many music players maintain copies of this metadata in a "music database." Of course, in doing so, the music database and the metadata can get out of sync, which can lead to all sorts of irritating disorganization. Note that there is a further opportunity to disorganize, since a music file will have a name (within the computer's file system), which could reflect, among other things, the name of the song, the track number from the album, the artist's name, and other information. This data may be found as well in the tags and the music database. And, of course, all three can be out of sync.

The three stages of music tagging

There are three stages of managing one's music collection where tag management (and here I'm including sorting out cover art) can happen:

When the music is ripped (doesn't count for music downloads) Once the music is ripped (or downloaded) but before it is put in the music library or libraries Once the music is in the music library

Based on these stages, aside from general-purpose tag editing tools, we can consider:

Music ripping software that enables good tag management right from the start Music players that incorporate tag editors for fixing problems while listening Music players that facilitate both ripping and tag editing

Considering that metadata occurs in three obvious places (within the music file itself, as a part of the file and directory names in the file system, and in the music player's music database), what first seems simple―editing music tags―can get suddenly quite complex and involved.

Music ripping and tagging

Inthis month's article, I'm going to take a look at readily available open source music ripping software, as seen from the perspective of its ability to manage tags. I spotted several music ripping tools in my distro's repositories: asunder, goobox, ripoff, ripperx, sound-juicer, crip, and ripit.

Besides getting the tags right, one critical concern when ripping CDs is getting the best rip possible. The open source tool cdparanoia is acclaimed by many as the best tool for CD ripping on linux. However, getting the best rip possible is not the only part of the story, and most ripping tools also organize the ripped data, convert it into a target format, and tag it.

Considering all of that, I have had a soft spot for asunder for quite some time now. Asunder provides a decent GUI-based experience, uses cdparanoia for ripping, converts to FLAC (and many other formats), organizes the ripped files in a configurable directory structure, and―to some extent, anyway―manages tags by looking up the CD in question on the CDDB music meta database .

Two things I have not been able to do with asunder, which I would love to have: the ability to attach cover art during the ripping process and the ability to deal with a few more tags, like "composer," for example. Asunder is pretty good at dealing with "artist" versus "album artist," which I seem to recall was a major pain in the neck at some point in the past.

As a music rippers go, asunder is pretty great, but it forces me to do the final tag and album cover adjustments either in a tag, editor or in a music player―not quite what I want.

I decided to give goobox a try. Once started, the application looks clean and GNOME-like. Nice. One thing immediately jumped out, as compared to asunder: goobox knows about cover art. The simplicity quickly had me wondering, could I instruct goobox where to put tracks? (In my case, because of asunder's limitations mentioned above, I stage them in ~/Music.rips .) But I could not set the directory structure, nor the file name layout, although the directory structure and naming convention used by goobox were okay with me. Moreover, I didn't seem to be able to save the cover art as a "cover.jpg" file in the generated directory. Finally, I could not tell whether goobox was using cdparanoia or not, and if
