Edit

$Song_id=$_GET["id"];

$my_delete="DELETE * FROM song_detail WHERE song_ID = '$Song_id' LIMIT 1 ";

$result=mysql_query($my_delete) or mysql_error();

echo "<h2 align=\"center\">Song Deleted Successfully!</h2>";

PHP:

to

$Song_id = $_GET["id"];

$my_delete = "DELETE FROM `song_detail` WHERE `song_ID` = '" . $Song_id . "' LIMIT 1";

$result = mysql_query($my_delete) or die(mysql_error());

echo "<h2 align=\"center\">Song Deleted Successfully!</h2>";
