Bug: ID3 COMM frame labeled as 'User Defined Text' instead of 'Comment'

[rpuneet]

Problem

ID3 Comment (COMM) frames are being extracted but labeled as "User Defined Text" instead of "Comment".

Comparison

Field	imx	exiftool
Tag Name	User Defined Text	Comment
Value	This is a test file...	This is a test file...

File

testdata/mp3/sample1_rich_metadata.mp3

Root Cause

The COMM frame handler is using the wrong tag name. COMM frames should be labeled "Comment", not "User Defined Text" (which is for TXXX frames).

Fix

In the ID3 parser COMM frame handler, change the tag name from "User Defined Text" to "Comment".

Priority

Low - Data is correct, just mislabeled
