You'd have to have made a note of the host's IP address, then you could try direct connecting to them to browse.

Or...you could just search for the song you've downloaded again. When it appears in the search results (it will have a ticked piece of paper icon), try to browse that host. The browse feature's not too reliable though, sometimes it'll work & sometimes not. It helps if you both have chat enabled & are not firewalled:wink:
