Tony Garnock-Jones released an Ajax jukebox written with Prototype on the frontend and Erlang on the backend.

You point the jukebox at one or more root URLs, which it then spiders, collecting URLs for MP3 and OGG files, which it puts into a simple flat-file database. Just expose, say, your iTunes folder via Apache, point the Jukebox at it, and you’re away.
It relies on mpg123 and ogg123’s support for playing HTTP-streamed MP3 and OGG files, respectively, rather than retrieving or playing the media itself.
The user interface is completely written in HTML+Javascript, using prototype for its event
binding and XMLHttpRequest support.
The server side of the application communicates with the user interface solely via JSON-RPC.
Erlang made a great platform for the server side of the application. Its support for clean, simple concurrency let me design the program in a very natural way.
