Before you worry about compiling your own version of SongPrint (suffice it to say that if you don't know how to do it, it's probably not the right thing for you), have a stab at MP3 Tag Studio. And a quick read through this FAQ entry.

Another option is that the latest registered version of MusicMatch is supposed to detect the tag information for you based on things like the file name and the song title.
