dbDelta not creating table (yes, once more)

I KNOW there are other posts relating to my issue, i read all of them and tried to see if the answer would change and tried a few ones, but I can't seem to create my table using it.

Here's my code (function is in object) and my sql querry:

public static function mq_install(){
    global $wpdb;
    require_once(constant('ABSPATH') . 'wp-admin/includes/upgrade.php');
    $table_name = $wpdb-prefix . 'zebra_musiquote';


    $charset_collate = $wpdb-get_charset_collate();

    $sql = "CREATE TABLE " . $table_name . "(
        id mediumint(9) NOT NULL AUTO_INCREMENT,
        from tinytext NOT NULL,
        artist tinytext NOT NULL,
        song tinytext NOT NULL,
        quote text NOT NULL,
        url tinytext NOT NULL,
        PRIMARY KEY  (id)
    ) ".$charset_collate.";";
    dbDelta( $sql );
}

Any suggestions? I'm desperate.
