If you like me have a large music collection in iTunes library, you may also encounter the same problem with me: edit multiple songs' tag or metadata. Generally, the songs imported from CD would have clean and correct tags, but there are still errors especially you are importing the old CDs or CDs of poor quality. So see how to tidy up your itunes music tag here.
Easy Steps to Tag Multiple Songs in iTunes
1. Select Multiple Files in iTunes. There are three methods to select multiple iTunes files.
a. Hold down Command or Shift (contiguous and non-contiguous) when click files.
b. Drag to select continuous multiple iTunes files.
c. Command + A or Ctrl + A (Mac and Windows) to select all files in the current view
2. Right click on any selected files and select Get Info, or simply Command+I
3. You will get a dialog saying as below.
4. Click Yes to open "Multiple Item Information" windows.
5. There are 4 tabs: Info, Video, Sorting and Options
Info: Edit multiple metadata including Artist, Album Artist, Album, Grouping, etc.
Video: This allows you to specify if the video is a movie, TV show or music video. You can also set episode information for TV shows.
Sorting: This is a technique you can use to customize searching for particular music.
Options: Similar to the Option tab in Get Info windows. By the Media Kind, you can move multiple items to another category, e.g. from Podcast to Music.
6. Simply edit the text field you want. There is no need to check the box. They will be checked once you start editing the tag information. But to disable a tag, just uncheck the box in case that you active it again later. Editing in the Option tab is similar.
7. Choose OK to apply changes to all selected tracks in iTunes.
