Download Accelerator Programs...what's good and what works well with MP3 Programs?

I was perusing download.com’s selection of free or free trial software and saw download accelerator programs. I’m a download nut for MP3s of concert bootlegs and using programs like gnucleus to get my booty. I’m wondering if these programs would be beneficial and what’s good.
Thanks,

MP3? Bootleg? I don’t think so. The Straight Dope has a policy of not helping people intheir copyright infringement. This thread is closed.
