What I do is this:
1) conduct a search for whatever song(s) I'm looking for;
2) tag them (right click titles which my search returns, select DOWNLOAD);
NOTE: I tag the file names *whether or not* they're presently available :shock:
3) go to transfers window;
4) make sure all "INCOMPLETE_" downloads are loaded in;
5) block everything in the transfers window that's not an active (or pending) transfer;
6) set titles for "look for sources every 10 minutes" and "auto enter queue" at 100;
7) go to work, go to sleep, go out for cocktails; and...
When I get home, it's like Christmas! All kinds of new music just waiting to be listened to.
