The BBC has launched a new Beta platform, Sound Index, that crawls through popular music sites and blogs ( Bebo, MySpace, Last.FM, iTunes, Google and YouTube ) capturing public info off of them about what people are listening to, watching, downloading, and logging on to. It does some math.. crunches the data and makes an index of the top 1000 tunes & artists placing them in order of their popularity. The Index is updated every 6 hours.
It works along the similar principle as Jonathan Harris’ and Sep Kamvar’s, We Feel Fine, which searches the internet every 20 minutes for people blogging about their feelings. And all pulled together in a very pretty way.
