"My ISP is capping my usage. Can I still listen?
Here's the maths. Our standard Windows Media streams are just 20k -
so, if you listen non-stop for 24 hours, you'll shift a total of 15 meg:
easily within the 1 gig limit that one UK ISP has put in place.
However, if you listen to our RealAudio broadband feed for 24 hours,
currently 128k, then you'll use up your entire 1 gig of bandwidth. (Not
that you'll listen 24 hours a day, of course.)
Most people listen to us online for around six hours a week, so our
advice is that it shouldn't make a major difference to the way you use
your internet connection - but, if you're worried, you ought to move your
ISP to one that doesn't have a usage cap.
While we understand ISPs wishing to make a good service for all of its
customers, don't believe usage caps and online radio stations mix well."
