When I go for 8 of one hosts songs I only grab two at a time. Successrate gets much higher if you do that. If some one went for 8 of my uploads at the same time and I noticed, I think I'd just kill the uploads to let someone grab a normal amount of simultaineous downloads.

If you grab two at a time and start the third when the first one finishes, you get a nice constant flow. Almost never transfer interupted etc.
