are they for game servers only, or can you run other things like shoutcast?

answer : the unamanged dedicated servers you can use how every you wish

so it wouldnt matter if you setup a "radio" station and end up having 1000 listeners, running a mp3 128bit stream ?

answer : You would be billed per mbit to 95th percentile over the month. http://en.wikipedia.org/wiki/Burstable_billing

cheers, im no good at math, so how much extra would someone be paying if they had a normal station with 30 people connected and left the server running 24/7 with a 96kbs stream ?

answer : If you had 30 listeners solid for 28 days would be 1120Gb approximately or around 4mbit
