http://media.kcrw.com/live/kcrwmusic.pls doesn't play anymore. But the location given in this file works (http://205.188.234.2:80/stream/1045).
If I try to playback the pls file on my linux console I get this error:
$ mpg123 http://media.kcrw.com/live/kcrwmusic.pls
[mpg123.c:560] error: Unknown mpeg MIME type audio/x-scpls - is it perhaps a playlist (use -@)?
[mpg123.c:561] error: If you know the stream is mpeg1/2 audio, then please report this as mpg123 bug

so If I do

$ mpg123 -@http://media.kcrw.com/live/kcrwmusic.pls

it just works fine.
