Pretty good idea and easy to monetize if people actually purchase through your site. I see this being less than 5% tho.

The logo concept is ok I suppose, but the overall presentation of your brand (logo+site) will significantly impact adoption of a product like this. I recommend you put some energy ($) into it... the logo reads like there's a 'T' in it btw.

I think you should enable some public features, for example a user can easily see any new releases within the last week. This will also boost your saturation on search engines.
