Basically, the Deezer website, where users can listen to streaming music and create playlists, will remain free of charge while users who would like better sound quality (up to 320 kb/s) and no more advertisements can opt to pay €4.99 per month for Deezer HQ. The Premium offering (€9.99 / month) is the most interesting though, since it gives users the opportunity to download a full-fledged Adobe AIR desktop application and lets them gain access to their accounts through a wide range of mobile devices, including the iPhone, iPod Touch and multiple Android-run and Blackberry devices.
Deezer also commissioned a study that showed more than 80% of its user base was keen on getting mobile access, while 40% was interested in better sound quality. The combination of in-browser, desktop client and listening to music on the go via mobile, has now made Deezer a great Spotify competitor. This is the type of convergence I keep wishing every online music service would offer.
