Redirect/URL question

[daysareb]

For now I am just getting familiar with the workings of uploading my content since I am new and have most of it figured out. However I have a redirect quesition.

Say I have two domains

Hardware.com
Music.com
(Obviously fictitious sites)

Hardware.com is my primary
Music.com is my add on.

how can I get my Url address in the tool bar to say music.com when I type and enter music.com instead of the redirect URL that says www.music.hardware.com?

Or am I going to have to open another primary account for this...
