In the need of a better way to explore my music collections (rhythmbox, last.fm etc...) I proposed a project at havealaunch.com http://bit.ly/akNPDV
Being a Ubuntu user I was wondering that maybe something similar exists where we can start or take inspiration from.

My idea is for a web tool but with a REST API so anyone can integrate and build a UI for desktop, mobile...

If someone in the community is interested or has suggestion, I am here to listen.

My intention is to start this kind of analysis on my rhythmbox collection which is a pretty easy to connect and manipulate xml file and populate some extra tag from last.fm or a single similar service.
