URL formatting.. can it be changed?

I've been listening to streaming internet radio in a virtual world client that has an input area for URL's for streaming radio.
The streams that function have url's that look like this one.
http://yp.shoutcast.com/sbin/tunein-station.pls?id=37833

They have numbers at the end .. and some of them have an IP address within the web address also.

How would I get a url that ends with text to translate to the format above? Or is that even possible?

I created my own playlist on two different sites today, which do provide sharing options, including URL's but they do not have that ID=#### ending format.

 

thanks for the reply

*sigh*

time to find another playlist making site
