The new site replaces a temporary one that had been in place since the music retailer was bought out of administration in April.
It focuses on curation, content and editorial in an attempt to push HMV’s “experience and authority”.
A newly recruited editorial team will maintain the content with contributions from staff across the company’s 142 UK stores.
The site is also integrated with HMV’s new digital music store, which launched last week, incorporating 30-second track previews into articles.
Caroline Pesch, who heads up the HMV.com team, said: “As a hub for entertainment, a key element of the site is the sense of community and ease of use for finding local and relevant information.
“In addition to editorial features and reviews store staff can post their own picks and tipsbased on what’s happening on a local level. This is just phase one of the new site; as it develops we will be introducing lots more new and exciting functionality. The volume of content available will grow daily.”
Code has worked with HMV for several years and was behind the company’s last major web overhaul, in 2007.
The new site will be rolled out to HMV Canada and HMV Ireland early next year.
