NPR Music, a beta site. While it's not a mass market answer, this site has the potential to give the likes of me a place to congregate. It seems truly eclectic.
At the top of the page is Yo Yo Ma, who talks about his favorite recordings of late. Among them he cites the New Pornographers, whose singer is Neko Case. There's a feature on Animal Collective, called "Unique, experimental, crazed."
A feature that caught my ear this week is called Project Song. In this edition, a songwriter named Stephin Merritt was sonically tracked as
he performed the piano, percussion and layered vocals of a new tune.
At NPR Music there's lots of free music: singles, concerts, interviews.
This might be the place that gets me back into buying CD's.
