There is a NBAR PDLM for Napster, Gnutella, Grokster, and a few others. But if your looking to block HTTP transfers with a .mp3 in the URL that could block traffic that is legit (some business-suitable audio clip, etc) and really isn't a solution. Also the user could zip/rar/arj up there mp3s instead, or use .ogg files, bring them into work on CD, whatever.
A better approach may to be use CAR or to rate-limit legit forms of traffic and all other traffic give 5% of the bandwidth. This way the non-conforming traffic is just slow and has lag. Users hate lag, but this could also cause more calls/emails to you. Depending on your traffic load and router model, memory, etc this could have a hit on the routers performance. In the end, its a no win situation since you're always chasing the latest internet applications and trying to block them. If the users are sophiscated they will get around the slowdown or change to a different method of obtaining the content. Just my opinion.
