Is there an online/web interface to search and list apt-get packages and see summaries and recommendations?

I'm looking for sort of an 'app-store' or Google Play store type functionality for apt-get packages. What I'd really like to do is select a category, like 'Music' or 'Internet' and see the list of available packages in that category with their summaries. It'd be even better if the packages had ratings or reviews. Does anything like this exist?
