Are you loading files using Blade?

{{ HTML::style(url, attributes, secure) }}
{{ HTML::script(url, attributes, secure) }}
{{ HTML::image(url, alt, attributes, secure) }}

Can you paste the view if you are

No , I dont want to use blade.And the problem is with .htacces file , I dont know how to enable it

You could try to load your data without using blade:

<?php echo public_path() . "/css/style.css"; ?>

You can still use HTML class without blade:

<?php echo HTML::script(url, attributes, secure) ?>

Looks like your script is looking for the files in directory 'music'... http://www.domain.com/music/cover.jpg

You must point them to the public-root:

<img src="../cover.jpg">

Maybe your server used nginx plugin or another same. You have setup extensions for images, javascript and style file.
You can maybe use

<?php echo HTML::script(url, attributes, secure) ?>
