OK. This is C-style code. It gets the info at the end of the mp3 file marked 
with the letters 'TAG'. Some of this may be truncated. I assume mfnm is an 
AnsiString holding the name of the MP3 file.

    FILE *fpj=fopen(mfnm.c_str(),"rb"); int nbry=0;
    char btgf[130],sngnm[35],artst[35],albm[35],yur[5],cmmnt[35];
    if (fpj)
    {
      if (fseek(fpj,-128,SEEK_END)==0) 
nbry=fread(btgf,sizeof(char),128,fpj);
      fclose(fpj);
    }
    if (nbry>0 && btgf[0]=='T' && btgf[1]=='A' && btgf[2]=='G')
    {
      strncpy(sngnm,&btgf[3],30*sizeof(char)); sngnm[30]='\0';
      strncpy(artst,&btgf[33],30*sizeof(char)); artst[30]='\0';
      strncpy(albm,&btgf[63],30*sizeof(char)); albm[30]='\0';
      strncpy(yur,&btgf[93],4*sizeof(char)); yur[4]='\0';
      strncpy(cmmnt,&btgf[97],30*sizeof(char)); cmmnt[30]='\0';
    }
