I came across a post on drupal.org which included a flash MP3 player that can use playlists. And it took me only a few minutes to realize this would be a great use of Views — to do something with Views that is very much an alternative output format.
So I did it, and added it to the Views Bonus Pack.
I checked this into the Views Bonus Pack tho of course it’ll take up to 8 hours for the tarball to regenerate. You can check out from CVS. It requires the audio module and this flash player. (which can be unpacked into the audio module directory).
Just as a note, I took the mp3 files from the demos offline; the playlist still shows up but no sound comes out. That's because my dev servers are hosted on my DSL and they were killing my bandwidth.
