Remove category base from WordPress url only for specific category
<p>I would like to remove the category base from Wordpress URL only for specific category. 
For example, i need to change:
mysite.com/category/blog
to
mysite.com/blog</p>

<p>but i want to keep other categories unchanged:
mysite.com/category/songs</p>

<p>I think that it could be achieved with some .htaccess rule, but I found some generic rules that remove the basic category in all the url.</p>
