Selecting tracks in a .pls file in WebRadio

Hi, all.

I have downloaded my favorite stations in DI.fm, and can play the .pls file in webradio, but i cannot figure out how to select a new station. when I play the PLS file, the first station starts to play, but I cannot select a new station in the list.

any ideas?

Thanks!
