I am going to, by request of CS, write some code for the site, so that there is only one download link for every song, but this link randomly selects one of the existing mirrors. This way one mirror won't be flooded with downloads, hopefully.
I'm not sure if that's a good idea, since my account will be suspended for the rest of the month if I exceed my bandwidth. If you could make a script that determines if the server is still up and/or offering the files, that would be ideal.
