You forgot to escape the exec command:
find . -name \*.mp3 -exec tar -cv {} \; | netcat hostip 1234

Besides that, -exec will also call tar for every file unless you terminate it 
with a + so in your example, you're creating a new file every time. Appending 
doesn't work when outputting to stdout so you could do something like this instead.

find . -name \*.mp3 -exec tar -cv {} + | netcat hostip 1234

However, with 10GB of MP3s, I'd imagine that the file list would be very long 
so that's probably not a good idea. If you don't mind having the files 
extracted at the other end, you could do something like this:

on the sender:
find . -name \*.mp3 -exec tar -c {} \; | netcat hostip 1234

on the receiver:
netcat -l -p 1234 | tar -xv
