Is it possible using AMXX to read ID3 tags (metadata?) from .mp3 files?

PHP Code:

#include <amxmodx>

public plugin_init()
{
    readDataFromMp3("sound/...")
}

readDataFromMp3(const fileName[])
{
    new filePointer = fopen(fileName, "rb")
    if(!filePointer)
    {
        server_print("failed to open file")
        return 0
    }
    
    fseek(filePointer, file_size(fileName) - 128, SEEK_SET)
    
    new tag[4]
    fread_blocks(filePointer, tag, charsmax(tag), BLOCK_CHAR)
    server_print("tag: %s", tag)

    new songTitle[31]
    fread_blocks(filePointer, songTitle, charsmax(songTitle), BLOCK_CHAR)
    server_print("songTitle: %s", songTitle)
    
    new artist[31]
    fread_blocks(filePointer, artist, charsmax(artist), BLOCK_CHAR)
    server_print("artist: %s", artist)
    
    new album[31]
    fread_blocks(filePointer, album, charsmax(album), BLOCK_CHAR)
    server_print("album: %s", album)
    
    new year[5]
    fread_blocks(filePointer, year, charsmax(year), BLOCK_CHAR)
    server_print("year: %s", year)
    
    new comment[31]
    fread_blocks(filePointer, comment, 30, BLOCK_CHAR)
    server_print("comment: %s", comment)
    
    new genre
    fread(filePointer, genre, BLOCK_BYTE)
    server_print("genre: %d", genre)
} 


Very basic and unpolished example, but it does the job. In general, you can open and ready any binary file if you know its structure(which you can find with a simple google search). You can also translate the genre byte into its string equivalent if you search for the list and build a table for it.
Here you can find another example(reading animation data from a mdl file): https://forums.alliedmods.net/showthread.php?t=310253 together with an explanation about what I did and why.

You can also review nvault utility as this does a similar task of reading binary data based on a defined file structure.
