bliss (full name elsten software bliss) is an intelligent, rules-driven, unique local music visual management software, developed with Java by Dan Gravell from United Kingdom. Unlike its peers, it runs on the basis of web browser and web data fetching. That is, the entire program only runs in the web browser rather than through an executable file, and requires an Internet connection.

We all like music, but sometimes we not only hope to enjoy the wonderful music on hearing, also won't pass any opportunities that can extend our music experience on vision. Of which the most basic and intuitive one is the music cover (album art), that can give us more perfect, even new music listening experience.
