[Resolvido] Inserir dados no banco

Alguem poderia me dar uma força neste erro.

Primeiro tenho meu formulario de inserção

<form action="cadastrar_sertanejo_db.php" method="post" enctype="multipart/form-data">
 <table width="500" border="0" cellspacing="3" cellpadding="0">
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Artista:</font> </strong></td>
 <td><input name="artista" type="text" size="60" MAXLENGTH="100"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Slogan:</font> </strong></td>
 <td><input name="slogan" type="text" size="60" MAXLENGTH="200"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">DDD:</font> </strong></td>
 <td><input name="ddd" type="text" size="2" MAXLENGTH="2"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Fone:</font> </strong></td>
 <td><input name="fone" type="text" size="8" MAXLENGTH="8"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Email:</font> </strong></td>
 <td><input name="email" type="text" size="60" MAXLENGTH="100"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Site:</font> </strong></td>
 <td><input name="site" type="text" size="60" MAXLENGTH="100"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Cidade:</font> </strong></td>
 <td><input name="cidade" type="text" size="60" MAXLENGTH="50"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Estado:</font> </strong></td>
 <td><input name="estado" type="text" size="60" MAXLENGTH="50"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Foto:</font> </strong></td>
 <td><input name="foto" type="file" value="100000" size="50"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Musica N:</font> </strong></td>
 <td><input name="nome_musica" type="text" size="60" MAXLENGTH="50"></td>
 </tr>
 <tr>
 <td align="right"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Musica:</font> </strong></td>
 <td><input name="musica" type="file" value="100000" size="50"></td>
 </tr>
 <tr>
 <td align="right" valign="top"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Conteudo:</font> </strong></td>
 <td> <textarea name="conteudo" cols="50" rows="10"></textarea></td>
 </tr>
 <tr>
 <td align="right"> </td>
 <td><input name="submit" type="submit" value="Cadastrar Sertanejo"></td>
 </tr>
 </table>
 </form>

Depois o arquivo que cadastra no banco:

<?php

include ("config_admin.php");

$artista = $_POST['artista'];
$slogan = $_POST['slogan'];
$ddd = $_POST['ddd'];
$fone = $_POST['fone'];
$email = $_POST['email'];
$site = $_POST['site'];
$cidade = $_POST['cidade'];
$estado = $_POST['estado'];

$foto = $_FILES['foto']['name'];
$tmpfoto = $_FILES['foto']['tmp_name'];

$nome_musica = $_POST['nome_musica'];
$musica = $_FILES['musica']['name'];
$tmpmusica = $_FILES['musica']['tmp_name'];
$conteudo = $_POST['conteudo'];

$diretorio = "foto_sertanejo/".$imagem;
$diretorio1 = "musica_sertanejo/".$imagem_musica;

if(move_uploaded_file($_FILES['foto']['tmp_name'], $diretorio . $_FILES['foto']['name']))
if(move_uploaded_file($_FILES['musica']['tmp_name'], $diretorio1 . $_FILES['musica']['name']))

$sql = "INSERT INTO sertanejo(
 artista,
 slogan,
 ddd,
 fone,
 email,
 site,
 cidade,
 estado,
 foto,
 nome_musica,
 musica,
 conteudo
 )
 VALUES (
 '$artista',
 '$slogan',
 '$ddd',
 '$fone',
 '$email',
 '$site',
 '$cidade',
 '$estado',
 '$foto',
 '$nome_musica',
 '$musica',
 '$conteudo'
 )";
$exe = mysql_query($sql) or die ("erro");
?>

O erro acontece nesta linha

$exe = mysql_query($sql) or die ("erro");
