because i dont know your skill level and the fact that you didnt post any code i would try to read id3v1 first or use a class that is already out there like
id3libid3V1 is easy to do all you have to do is read the last 128 bytes of the file
the layout is
CODE
ID3v1 identification -> 3 characters (the word "TAG")
Song Title -> 30 characters
Artist -> 30 characters
Album -> 30 characters
Year -> 4 characters
Comment -> 30 characters
Genre -> 1 byte
there is alot more to id3v2 but here is the
structure of id3v2
