well, you should have a look here: http://laravel.com/docs/eloquent#timestamps and here http://laravel.com/docs/schema

long storry short. -> In your model (Music), add the following somewhere near the top

 public $timestamps = false;

OR in your migration, add

$table->timestamps();

and rerun the migration

So did you read the docs? http://laravel.com/docs/eloquent

Once a model is defined, you are ready to start retrieving and creating records in your table. Note that you will need to place updated_at and created_at columns on your table by default. If you do not wish to have these columns automatically maintained, set the $timestamps property on your model to false.

If you want timestamp, just add $table->timestamps(); to your migration.

Oh. Now i feel stupid!
