As I understand it, this all depends on the availability of each of those x hosts -- so if a song is hosted by 4 people, limewire tries to connect to each. If you watch the in the download folder you will see as it checks the different addresses). Just as many times when you chose a song with only one host available, you may go into requery or busy, so with multiple hosts all or most of them may be busy. Limewire downloads from as many as are currently available and respond to your request -- if it's able to connect to more than one, it will say "Downloading from 2 hosts" or "Downloading from 3 hosts" or whatever, and you will see generally faster downloads on those.
