Question about Internet Radio on 6.0

[Rillithain]

Hi,
I recently upgraded to 6.0 version. I noticed that when I click the little arrow to the right of the URL for my Internet Radio entry, it opens a new window. Does the mean I've gone to that radio stations website, and that there is now no way to just play it within the subsonic window like previous versions?
Thanks,
Rillithain
