I am using a redirection wordpress plugin in Wordpress that accepts regex and I wish to 301 a whole directory to new things.

http://www.example.com/tag/exampletag1/ &lifier http://www.example.com/tag/exampletag2/

to

http://www.example.com/music/exampletag1/ &lifier http://www.example.com/music/exampletag2/

Is possible? You will find a number of tags so I'd rather not do that by hand. Would this be simpler to complete within the htaccess file?

Anything which get me pointed in the right direction is excellent.

The next ruleset in .htaccess would redirect /tag/ to /music/

RewriteEngine On
RewriteRule ^/tag/(.*) /music/$1 [R=301]

[R=301] signifies an exterior redirect with HTTP status code 301.
