PowerShell.nu

Structuring up you Music Library can be a rather time consuming task. You can however script this rather easily through PowerShell using the taglib-sharp library.

Let’s start off by downloading the Tag-Lib Library
Next, We have to Load the Assembly from PowerShell in order to access the Classes.

PS > $TagLib = "C:\taglib\Libraries\taglib-sharp.dll"

PS > [System.Reflection.Assembly]::LoadFile($TagLib)


GAC    Version        Location
---    -------        --------
False  v2.0.50727     C:\taglib\Libraries\taglib-sharp.dll

Now that we’ve loaded the dll, we need a music file that we want to set properties on, in this example I’m going to use a mp3 file. If we check out the properties on the mp3 file, we can see that nothing is set.

Let’s change this through PowerShell. We have to create a variable using the [Taglib.File] Class and use the filepath as an argument to the Create() method.

PS > $Media  =  [TagLib.File]::Create("C:\Music\My Song.mp3")

The object contains a couple of Properties.

PS > $Media


Tag                    : TagLib.NonContainer.Tag
Properties             : TagLib.Properties
TagTypesOnDisk         : Id3v1, Id3v2
TagTypes               : Id3v1, Id3v2
Name                   : C:\temp\My Song.mp3
MimeType               : taglib/mp3
Tell                   : 0
Length                 : 0
InvariantStartPosition : 4608
InvariantEndPosition   : 7109078
Mode                   : Closed

The one that We’re interested in is the Tag property, which contains additional underlaying properties and methods. Let’s check it out:

PS > $Media.Tag


StartTag             : TagLib.NonContainer.StartTag
EndTag               : TagLib.NonContainer.EndTag
TagTypes             : Id3v1, Id3v2
Tags                 : {Audiograbber 1.83.01, LAME d
                       v2.PrivateFrame TagLib.Id3v2.

JoinedAlbumArtists   :
JoinedPerformers     :
JoinedPerformersSort :
JoinedComposers      :
JoinedGenres         :

Let’s go ahead and set a couple of Values.

PS > $Media.Tag.Performers = "Goude"
PS > $Media.Tag.AlbumArtists = "Goude"
PS > $Media.Tag.Artists = "Goude"
PS > $Media.Tag.Album = "My Album"
PS > $Media.Tag.Genres = "Rock"
PS > $Media.Tag.Track = "1"
PS > $Media.Tag.Title = "My Song"
PS > $Media.Tag.Year = "2009"
PS > $Media.Tag.Comment = "PowerShell Demo"
PS > $Media.Save()

If we check out the file properties through Explorer we’ll see that the properties are set on the file.

So, editing one file is easy, but what if you want to edit a couple of thousand files..

When I did this on my Media Files i used the Folder and File Names as reference. The folder and file structure was set up accordingly:

C:\Music\Rock\Artist1 – Album\01 – First Song.mp3
C:\Music\Rock\Artist1 – Album\02 – Second Song.mp3
C:\Music\Rock\Artist2 – Album\01 – First Song.mp3

So with this information i could make a script that Used this information in order to set the Tags. The script uses the “Rock” folder name as Genre, Then it Splits the “Artist – Album” folder and sets Artist = Artist and Album = Album, finally it splits the file name “01 – First Song.mp3″ and sets Track = 01 and Title = First Song. I’ve also error handling in the script so that You can follow up on files that didn’t pass through the script.

Examples on Running the script:

PS > Set-Media.ps1 -Folder C:\MyMusic\Rock -LogFile C:\Log\SetMediaLog.txt

Note! You can always modify the script to fit your own environment and folder structure.
