How do I open .pls files?

I downloaded a .pls file for an online radio, but I can't open it. Winamp, VLC player all fail when opening, and [A Online Radio](https://play.google.com/store/apps/details?id=com.leadapps.android.radio) which according to the description can open this type doesn't show up in the "open with this" list. What are my options?
