Sirius Satellite radio - using up a lot of bandwidth/Internet

I was looking at the usage logs for the Internet at a client today.  Nothing too specific, just a general 'Usage by IP' report.  I have one client who uses multiples on multiples of Internet compared to others.  Using numbers from this report, in the last month, his computer has downloaded 60 GB of data, compared to an office average of anywhere from 1 - 4 GB.  All of his usage is Port 80.  He uses the Sirius Satellite Radio player.

I have other people at this office who also listen to on-line radio, but their usage is nowhere near this user's.

Is there something special about Sirius radio?

A couple of other notes:
- I have double checked his PC, and there is nothing else going on (no spam viruses, etc.)
- we have a super Internet connection (10 MB up and down)

Any helpful insight would be appreciated.

Thanks,

TN

Depending on the channel and time of day, Sirius can have quality of up to 192kbps I beleive, above a lot of average on-line radio.  Also if this user listens all day, everyday, I can certainly see why thier usage will be higher.  

That being said, say the user listens 8 hours a day, for an average of 22 working days a month and the average quality is 128kbps (kilobits per second), we can do a bit of calculation:

128kbps = 16 Kb/s (kilobytes per second)
16 Kb/s x 60 seconds = 960 Kb per minute
x 60 minutes = 57600 Kb per hour
x 8 hours = 460800 Kb per day
x 22 days = 10137600 Kb per month
= 9900 Mb per month
= 9.66 Gb per month

Even at this high calculation, that would only account for 1/6 of thier usage.

Keep in ming that a lot of peer-peer file sharing can be forced to go over port 80 as well.  As well as a lot of other downloads off of the internet will come over port 80 as well.
