Examples

Compile
This is obvious, just copy the code below to main.c and: 

gcc -o id3 main.c

Using

~/Projects/mp3tagread$ ./id3 /media/160gb/e/MP3s/Dead\ Prez\ -\ Hip-Hop.mp3 
title: Hip-Hop
artist: Dead Prez
album: Lets Get Free
year: 2001                            
comment:                             
genre: 12

Getting just one field 

~/Projects/mp3tagread$ ./id3 /media/160gb/e/MP3s/Dead\ Prez\ -\ Hip-Hop.mp3 | grep "^title\:"
title: Hip-Hop

Translating SJIS to UTF-8
Requires the recode command, but can be used to translate id3 tags :D 

~/Projects/mp3tagread$ ./id3 ~/Music/th03_東方夢時空\ ～\ Phantasmagoria\ \
of\ Dim.Dream/th03_08-夢消失　～Lost\ \
Dream.mp3 | grep "^title\:" | recode -f SJIS...UTF-8
title: 夢消失　〜Lost Dream          ＺＵＮ（太田順也）            東方夢時空

(please note: the last example is entirely why i wrote this :P)
