Download booster?
 

I have a connection that sometimes permits download speeds of up to 50kbps up 'til now, but the usual downloading speed varies between 1kbps and 13kbs.
I recently found that when the download speed seems to get low and I start getting "Waiting Xs for Y busy" statuses, if I search and download a relatively popular song, suddenly the download speeds max themselves out again only to drop when the song is fully downloaded.
I just wanna know if that is only my impression made by coincidence or actually true.

Oh, I forgot. Also, when I get the "Waiting Xs for Y busy" statuses, if I research the file then the status reverts to "Downloading...".That is, if for example I'm downloading File A and the download stops because it "waits for busy", then I retype the search on the search field, relaunch it and , after getting some results, the download starts again.
