Comment 4 for bug 21579

sander@sander:~$ grep pls /etc/gnome/defaults.list
audio/x-scpls=rhythmbox.desktop
sander@sander:~$

That means Rhytmbox is associated with pls files, correct? But still, I also
tried other websites with pls file links, but it doesn't open them. But to be
more precise, I noticed that when I click a link to a pls file in Epiphany, it
does open Rhytmbox, but in Rhytmbox the stream isn't added to the radio list,
and the stream doesn't play.
