Managing Track Info
UPDATED: Enter Description Tag for Selected v2.0
iTunes 12 no longer provides a means for editing the Description tag of multiple-selected tracks. This oldie, Enter Description Text for Selected, was just updated to v2.0 and will let you enter text for the Description tag of the selected tracks.
Technically (according to iTunes), the Description tag isn't supposed to be applicable to music tracks. But all track entries have an AppleScript description property.
UPDATED: Append to Selected Tag v4.0
Append to Selected Tag v4.0 can append the same user-entered text to the beginning or ending of the existing text in the chosen tag (Song Name, Artist, Album Artist, Album, Composer, Comments, Genre, Grouping or Show Name, and their Sort siblings) in each selected track.
For tags other than "Song Name" and "Show Name", this script may be just slightly less involved than performing a multi-edit on the selected tracks. On the other hand, unlike using the modal "Get Info" panel in iTunes, tracks remain accessible and selectable.
This latest version adds support for OS X 10.10 Yosemite and iTunes 12 (and drops support for pre-Mountain Lion), provides a "Check for Update" menu command, and has other minor tweaks.

UPDATED: This Tag That Tag v3.4
This Tag That Tag v3.4 will assist with swapping, copying, and appending data between two user-chosen tags in selected tracks or tracks in the selected playlist:
Swap - swap data between tags, ex: ARTIST<->COMPOSER
Copy - copy data from one to another tag, ex: ARTIST->COMPOSER ARTIST
Append - append data from one tag to the end of another, ex: ARTIST->COMPOSER - ARTIST
Prepend - prepend data from one tag to the beginning of another, ex: ARTIST->ARTIST - COMPOSER
The latter three actions also provide an option to delete the info from the first tag after the copy.
This latest version adds "Category", "Description" and "Episode ID" text tags as options and a few minor tweaks and adjustments.

UPDATED: Search-Replace Tag Text v3.5
Search-Replace Tag Text v3.5 performs a search-and-replace on the text in your choice of tag (Song Name, Show, Artist, Album Artist, Album, Composer, Comments, Genre, or Grouping) in the selected tracks or all the tracks in the selected Playlist. Features case sensitivity and whole word match options and dry run preview.
This new version stores the dry run setting between launches, has some additional minor tweaks and is ready for Mavericks.

NEW: Multi-Media Items Edit
For reasons not yet clear, as of iTunes 11.1, multi-item editing is no longer possible when a track selection contains mixed media kinds, audio and PDF for example. Kirk explains the matter here.
The script Multi-Media Items Edit provides basic tag editing for a selection of tracks of any media kind.
Wondering why your favorite tag or option isn't included? Just keeping it simple, friend-o.
UPDATED: Search-Replace Tag Text v3.4
Search-Replace Tag Text performs a search-and-replace with the text in your choice of tag (Song Name, Show, Artist, Album Artist, Album, Composer, Comments, Genre, or Grouping) in the selected tracks or all the tracks in the selected Playlist. Features case sensitivity and whole word match options and dry run preview.
This latest version enables the window to be resized horizontally in order to expand the width of text entry fields.
UPDATED: Remove n Characters From Front or Back v4.6
Remove n Characters From Front or Back lets you delete a specified number of characters from either the beginning or the ending of the Song Name, Album, Artist, Comments, Composer or Show tag (or their "Sort" siblings) of each selected track. For example, delete the initial digits and the space from "01 First Track", "02 Second Track", and so on.
This updated version caps the maximum number of characters to the length of the shortest text in the selected tags, preventing inadvertent deletion of tag text that may be shorter than the user-set number of characters to remove.
UPDATED: Search-Replace Tag Text v3.3
Search-Replace Tag Text v3.3 performs a search-and-replace with the text in your choice of tag (Song Name, Show, Artist, Album Artist, Album, Composer, Comments, Genre, or Grouping) in the selected tracks or all the tracks in the selected Playlist. Features case sensitivity and whole word match options and dry run preview.
The latest version sports conventional search fields and has some minor code tweaks.
UPDATED: This Tag That Tag v3.1
This Tag That Tag will assist with swapping, copying, and appending data between two user-chosen tags in selected tracks or tracks in the selected playlist:
Swap - swap data between tags, ex: ARTIST<->COMPOSER
Copy - copy data from one to another tag, ex: ARTIST->COMPOSER ARTIST
Append - append data from one tag to the end of another, ex: ARTIST->COMPOSER - ARTIST
Prepend - prepend data from one tag to the beginning of another, ex: ARTIST->ARTIST - COMPOSER
The latter three actions also provide an option to delete the info from the first tag after the copy.
This latest version allows numerical tag data to be copied (for example, the Year tag's data can be copied to the Comments tag).
