Audacious - OLD, PLEASE USE GITHUB DISCUSSIONS/ISSUES

While trying to play a di.fm stream on my Ubuntu 12.10 Audacious install, I am unable to play with the pls file provided by di.fm. The pls file contains:
[playlist]
NumberOfEntries=7
File1=http://stream-70.shoutcast.com:80/listen.pls?sid=1
Title1=Digitally Imported - Vocal Trance

File7=http://stream-196.shoutcast.com:80/listen.pls?sid=1

Upon trying to play one of the streams the error "No decoder found for http://stream-70.shoutcast.com:80/listen.pls?sid=1." is received.

I then tried to manually open the URL of http://stream-70.shoutcast.com:80/listen.pls?sid=1 but to no avail. Finally, after some assistance from the IRC channel, we managed to get it going by dropping the ?sid=1 portion of the URL.
