Developer API help

Getting some weird behaviour, and wondering if I have missed something in the API docs.

I run my query, and in the response, I get station ID, and with this, Base URLs.

To "tune" to the station, I then need to make a web request to get the stream URL in playlist format (either PLS, M3U or XSPF) like so:

String url = "http://yp.shoutcast.com/"+ currentSelectedStation.getBase() + "?id=" + currentSelectedStation.getStatuionID() ;

This works for some stations, but sometimes the PLS file contains the actual stream, and sometimes it takes me to the shoutcast status page for the stream (???)

For example:

I found a station titled "Metal Express Radio"

and got the pls file:

code:
http://yp.shoutcast.com//sbin/tunein-station.pls?id=1376628

The URL in here is not the stream, it links to the stream status page:

code:
http://5.135.154.69:11590

What have I missed here? Thanks.
