in case you haven't seen already...

if you are on hi-speed, you can download 1 song at say 30kbs(from 1 host). if you have 8 hosts, it increases the download speed to upwards of 200-300 kbs. (just general figures)

obviously if given a choice, download from the highest number you see that matches what you are looking for.

p.s. can't remember, does it make a difference with dial-up??
