Pandora has a local app you can install on a PC and stream audio.  How can I block this?  I have blocked the actual website, www.pandora.com, on my firewall but now people have started installing this app to get around it.  I want to block internet radio 100%..

download the app yourself, start streaming, go to a command prompt, run netstat -b to see what IP and port(s) it's talking on, block those in your firewall.

since it probably has multiple connection points, lather rinse repeat until it stops working altogether.

either do all that, or, if you're on a windows network, create a gpo to prevent them from running the app at all
Hi I did an nslookup and found this
pandora.com     internet address = 208.85.40.20
pandora.com     internet address = 208.85.40.50
pandora.com     internet address = 208.85.40.80

you block all the above three ips on your firewall and it will be 100% blocked.

Cheers
Some more clues...the following are the dns servers for pandora and remember dns queries are udp.
pandora.com     nameserver = ns-c.pnap.net
pandora.com     nameserver = ns1.p20.dynect.net
pandora.com     nameserver = ns-d.pnap.net
pandora.com     nameserver = ns3.pandora.com
pandora.com     nameserver = ns.savagebeast.com
pandora.com     nameserver = ns-b.pnap.net
pandora.com     nameserver = ns-a.pnap.net

ns1.p20.dynect.net      internet address = 208.78.70.20
ns-a.pnap.net   internet address = 64.94.123.4
ns-b.pnap.net   internet address = 64.94.123.36
ns-c.pnap.net   internet address = 64.95.61.4
ns-d.pnap.net   internet address = 64.95.61.36

if you can stop your dns server from resolving you can still block .

cheers
