NPR relaunched NPR Music yesterday, a collaboration of 12 local NPR stations, with a new, Flash-based media player. Here's their intro to the new features.

Read/Write Web raves,

In testing the site I was able to quickly assemble a playlist of both single songs and hour-long concert performances. Playback was very smooth in most circumstances though switching between multiple hour-long recordings sometimes took awhile to buffer.

In addition to the ability to quickly put together your own playlists, the new NPR Music site highlights a wide variety of pre-built playlists: from Yo-Yo Ma's Top Five Faves to five of the best songs recently released in Africa, courtesy of the hosts of the show "All Songs Considered." In an increasingly unmanageable world, expert aggregation in any field is a top-notch value add.
